PURPOSE: Evaluate and
implement safety and health interventions that reduce workload or workplace
hazards, reorganize the work, and/or provide new information to change how
workplace hazards are managed. Enhance the development of cross-cutting
research and interventions that focus on the complex relationship among
workload, stress, and risks for injury in agriculture, construction, and
mining.
RESEARCH SUMMARY:
Agriculture, construction, and mining are three of the most hazardous industries
in the United States. These three industries consistently rank among the
top four for deaths per 100,000 workers. In addition, children and adolescents
are at high risk for work-related deaths and injuries in family farming
and fishing operations. Standard operating procedures in hazardous industries
typically reflect the specific demands and requirements of the tools and
hazards that are present in the work environment. But often how these procedures
are carried out on the job reflects other, more immediate, demands to maintain
productivity.
The work crew performance model (WCPM), developed by the Pittsburgh Research
Laboratory, is being implemented in agriculture and construction. Ladder
set-up and use has been selected as an application of this model to a small
construction setting, while a County Cooperative Extension project dealing
with beef cattle farming has been selected to apply the model to agriculture.
In the construction component, extension ladder set-up and use checklists
have been prepared for evaluation using (1) training at construction sites
through a 10-minute toolbox talk, (2) reminders posted on the ladders or
on a pocket card about everyday use, and (3) investigations of occupational
injuries and fatalities involving extension ladders.
The application of the WCPM has shown that there is a great deal of variability
in both set-up and use. The checklists have been designed to address this
problem. In FY03, the ladder set-up and use checklists will be evaluated
and validated prior to submission for printing as NIOSH numbered documents.
The results from this interdisciplinary effort are expected to lead to (1)
interactive tools for workers in the industries under study, (2) improved
communication and collaboration among NIOSH scientists and other safety
and health professionals working in hazardous industries, and (3) an on-going
exploration of cross-cutting approaches to common problems in the three
industries.

PURPOSE: Further field
development, evaluation, and demonstration of interventions aimed at reducing
worker exposure to equipment and moving vehicles operating inside the boundaries
of work zones and other work areas.
RESEARCH SUMMARY:
Highway and street construction workers are at risk of fatal and serious
nonfatal injuries when working near passing motorists, construction vehicles,
and equipment. From 1992-1998, 841 highway and street construction workers
were fatally injured. In 465 of these 841 cases (55%), the death was either
vehicle- or equipment-related and either clearly or probably occurred in
the work zone. In 318 of the 465 vehicle and equipment-related fatalities
within work zones, a worker on foot was struck by a vehicle. Victims were
as likely to be struck by a construction vehicle as by a passing traffic
vehicle.
Road construction is expected to increase by 40% due to increases in federal
highway funds under the Transportation Equity Act for the 21st Century.
Work zone safety is a priority for labor, industry, and federal and state
agency officials who express concern that increases in road construction
and structural changes in the industry will lead to increases in worker
fatalities. Internal traffic control plans and a variety of proximity warning
devices are promising, yet unproven, interventions for preventing fatalities
and injuries associated with mobile vehicles and equipment. If proven to
be effective, adoption of these interventions could substantially reduce
exposure of workers to moving vehicles and equipment, thus reducing fatalities
and injuries.
This collaborative project involves the Division of Safety Research, the
Pittsburgh Research Laboratory, and the Spokane Research Laboratory. The
project consists of four phases: evaluation methods development, intervention
development, intervention evaluation and demonstration, and information
dissemination and technology transfer. Specific aims include evaluation
and design of traffic control plans and methods to reduce worker exposure
to moving equipment; assessment of off-the-shelf proximity warning sensors
on construction equipment; modification and evaluation of the Hazardous
Area Signaling and Ranging Device (HASARD) to prevent collisions between
pedestrian workers and construction equipment; and design, development,
and assessment of a work zone analysis system for recording and analyzing
time and motion studies.

PURPOSE: Evaluate
the effectiveness of two interventions on the reduction of travel speeds
in highway work zones.
RESEARCH SUMMARY:
While the injury rate in the U.S. construction industry has declined by
2.9% a year and the fatality rate in the U.S. transportation industry has
declined by 3.2% a year, the number of severe injuries and fatalities in
highway work zones has stayed constant at approximately 37,000 and 800 a
year, respectively, for the last several years, at a cost of $4.0 billion
a year. Excessive speed and driver inattention are considered to be the
two major causes of highway work zone accidents. The effectiveness of two
interventions—rumble strips and variable message signs—are expected to reduce
50% of the injuries and fatalities caused by "excessive speed" and "driver
inattention." Rumble strips consist of raised asphalt, pavement grooves,
and masking tape. Messages include work zone speed and driver speed. Active
speed controls were applied on 65-mph highways in western New York during
1999-2001. All highways had posted speed limits of 45 mph in work zones.
Pneumatic road tubes with portable traffic counters were used to monitor
speeds. Six types of variable message signs were tested; the effectiveness
of each type is given below in order of effectiveness.
- WORK ZONE 45 MPH - PLEASE SLOW DOWN—reduced vehicle speeds by 6 mph.
- WORK ZONE MAXIMUM SPEED 45 MPH - BE PREPARED TO STOP—reduced passenger
car speeds by 4.2 to 5.5 mph and average speeds of all vehicles by 2.9
to 3.7 mph.
- WORK ZONE 45 MPH-STATE POLICE ENFORCED—reduced vehicle speeds by
5 mph.
- YOUR SPEED, X MPH-reduced vehicle speeds by 4 mph.
- RIGHT LANE CLOSED-KEEP LEFT and LEFT LANE CLOSED- KEEP RIGHT—were
both effective in reducing vehicle speeds by 2.3 mph.
The tests also showed that the signs reduced the percentage of vehicles
traveling above 45 mph by about 8%.
Rumble strips proved effective for the driving lane only, reducing average
speeds by 1.2 to 2.2 mph. A different brand of rumble strips combined with
POLICE ENFORCEMENT signs reduced vehicle speeds significantly, by 3.0 to
4.5 mph, while standard deviations of the speed of all vehicles decreased
by 25% in both in the driving and passing lanes.

PURPOSE: Investigate
the range of interventions used to decrease silica exposure in the sandblasting
industry and study their health and economic impacts.
RESEARCH SUMMARY:
Silicosis is a disabling and often fatal lung disease that is completely
preventable. The recent designation of silica as a lung carcinogen by the
International Agency for Research on Cancer (IARC) makes the control of
silica urgent. The connection between silica and tuberculosis is well known,
and, with the rise of drug-resistant tuberculosis, the need to control silica
is clear.
Sandblasting results in high silica exposures. NIOSH has produced excellent
research on the industrial hygiene aspects of using blasting substitutes,
yet there has been little research into the health effects of substitutes
not associated with chemical exposures.
With all the much-needed focus on technologies to reduce silica exposure,
we must be mindful that we do not introduce new hazards into the workplace.
There have been numerous cases of unintended consequences resulting from
well-intentioned interventions because the focus has been on controlling
a single hazard rather than assessing the full range of impacts in a work
environment. To evaluate an intervention fully, we need an integrated approach
to the workplace. Furthermore, before any research can be useful in helping
contractors decide which method to choose, the economics of each technology
must be assessed.
This study will address the potential health and economic impacts associated
with substituting other materials for silica sand and the technologies to
deliver those substitutes in abrasive blasting.

PURPOSE:
Lower injuries in construction through the use of methods that can be easily
replicated by the entire construction industry. Significantly reduce traumatic
injuries related to the great majority of construction accidents by focusing
on work planning and specific work practices and controls.
RESEARCH SUMMARY:
The proposal aims to show that introducing strong injury prevention methods
at the level of the subcontractor can improve safety practices and lower
the number of injuries. In the initial phase of the intervention, information
will be gathered on industry best practices, which will then form the basis
for the intervention safety program. Contractor, foreman, and trade worker
responsibilities will be specified. Targeted injuries will include falls,
electrocutions, and "struck by" and "caught between pieces of equipment"
accident types that account for 90% of construction fatalities.
Forty medium-to-large contractors (that is, contractors with more than 50
full-time- equivalent employees) who do not currently have a strong safety
program will be enlisted. These contractors will be drawn from four geographical
regions and from a full range of trades represented by the AFL-CIO Building
and Construction Trades Department. A like number and type of contractors
will be sought as controls.
The intervention will consist of—
- Provision of an OSHA-compliant safety program,
- Provision of supporting training materials,
- Bi-monthly site visits by researchers to audit program compliance,
- Semi-annual progress reports to participating contractors and building
trades councils, and
- Collection and analysis of injury data based on OSHA logs and hours
worked at the construction sites. While injury data will also be sought
from control contractors, experience has shown this to be problematic.
The expectation is that work conditions and safety practices at the intervention
sites will improve significantly compared with safety practices and work
conditions at the control sites. It is also anticipated that injury rates
at the intervention sites will decline significantly.

PURPOSE:
Evaluate the effectiveness of job site interventions aimed at the reduction
of contact dermatitis among construction workers and the economic impact
of occupational contact dermatitis in construction workers.
RESEARCH SUMMARY:
As described in the National Occupational Research Agenda, skin diseases
are the leading nontrauma-related occupational illnesses in the United States,
accounting for 12% to 15% of all occupational illnesses. The exact incidence
rate is unclear; estimates range from 67 to 1,700 cases per 100,000. Skin
diseases may be recurrent and chronic and result in high direct and indirect
costs that may reach up to $1 billion annually. The most common occupational
skin diseases are allergic and irritant contact dermatitis, which are preventable
diseases. Construction workers are exposed to many harmful substances that
can cause contact dermatitis, including portland cement, epoxies, solvents,
and preservatives.
Some believe that skin problems affect up to 80% of the workers who have
continual contact with products containing portland cement. Found in concrete,
mortar, and related construction materials, portland cement is known to
cause irritant and allergic contact dermatitis. The alkalinity of wet cement
contributes to irritant contact dermatitis, and hexavalent chromium is a
strong sensitizing agent responsible for allergic contact dermatitis in
cement workers worldwide.
In this project, surveillance activities involve analyses of data from the
published literature, occupational exposure surveys, and collection of injury
and illness statistics to identify construction workers' exposure to potential
dermal hazards. Economic analyses of jobsite and industry-wide interventions
are performed, as well as economic characterization of the impact of disease
on contractors, workers, workers' compensation systems, private insurance,
and society. These interventions are also evaluated as to their effectiveness
in reducing contact dermatitis symptoms among the target population.
Materials have been developed aimed at employers, workers, and safety and
health professionals regarding the issues and recommended controls relating
to contact dermatitis caused by portland cement. A training program has
been developed for use by union training centers and employers whose workers
come in contact with wet portland cement. Information and publications about
contact dermatitis are disseminated to the construction community through
a number of CPWR avenues, including employer associations, international
unions representing workers in the construction industry, and CPWR's electronic
library of construction occupational safety and health (http://www.elcosh.org).

PURPOSE:
Implementation and evaluation of a modified behavior-based work observation
and sampling process to increase construction worker involvement in safety
and improve hazard recognition and abatement.
RESEARCH SUMMARY:
Construction projects are typically complex undertakings that require extensive
coordination among many contractors, trades, and work tasks. Traditional
command and control management structures rely on safety policies and procedures
developed by the construction manager or general contractor. The transient
nature of construction sites means that environmental conditions change
rapidly and worker turnover is high. Efforts to involve workers in the safety
process may take place through toolbox meetings, safety committees, or suggestion
systems, but the high turnover of workers on a construction site inhibits
continuity of participation.
This study introduced and evaluated a crew-based work observation process
at a large construction site in the Pacific Northwest. The process, Best
Practices Sampling (BPS), draws on work sampling and observation elements
from behavior-based safety programs implemented in fixed industry. The distinguishing
feature of BPS is that the crew is responsible for designating the critical
safety items it will monitor and defining best-practice criteria.
Crews from four trade contractors representing four different crafts and
working under a single general contractor on the same project participated
in the study. Following a 2-hour training session during which crew members
were introduced to performance management and self-management concepts,
the crew or work team, in a facilitated process, developed a list of best
practices required for safe performance of their work tasks. Each crew member
was instructed to take 5 to 10 minutes at random every day to observe the
work area, tools and equipment, work methods, and worker behavior. The observer
noted each time an item was observed and marked it either "best practice"
or "needs improvement." All crew members were expected to participate in
the development of this list and in defining the best practice for each
item based on their knowledge and experience in the trade. Sampling cards
also provided space for written comments on any safety matter observed.
The initial findings suggest that worker-based safety processes hold great
potential but are extremely fragile. Crews that perceived the highest levels
of organizational support for the intervention provided the highest number
and highest quality comments concerning existing safety procedures and conditions.
Likewise, perceived supervisor and foreman support for the BPS process was
also associated with higher levels of BPS activity among crew members.
Results were largely consistent with the determinants of success for other
nonhealth- and safety-related worker involvement programs in other industries,
suggesting that general research on worker involvement may be relevant to
worker-centered safety interventions.

PURPOSE:
Evaluate processes and outcomes of a collaborative safety-in-design process
implemented by owners, construction managers, and design firms to reduce
safety hazards in all life cycles of the facility being constructed.
RESEARCH SUMMARY:
Evidence from studies of construction accidents and injuries suggests that
a significant proportion of such events originates upstream of the building
process, i.e., they are connected to such processes as planning, scheduling,
and design. One European analysis attributed up to 60% of construction accidents
to decisions or behaviors that took place prior to the construction work
itself.
In the course of a number of construction projects, Intel Corp. incorporated
elements of a safety-in-design approach. These include "lessons learned"
and development of a safety-in-design checklist based on issues identified
in the construction and operation phases of earlier buildings. In the design
of a prototype semiconductor factory, the company, in collaboration with
the project's construction manager and design firm, launched a comprehensive
process of safety in design, labeled Life Cycle Safety (LCS), which introduced
explicit evaluations of design options in programming and three stages of
detailed design. LCS is intended to look at all cycles of the structure:
construction, commissioning, operations, maintenance, retrofit, and demolition.
A major goal is to involve trade contractors with relevant experience prior
to construction when their input can identify potential risks at stages
where these risks can be addressed by design changes or, if not, be mitigated
in the field. Focus groups were held with journeymen and superintendents
from four crafts in the early stages of LCS to develop lists of design considerations
having safety, quality, and productivity implications.
To evaluate this process, semi-structured interviews were conducted with
a large sample of members of the disciplinary work groups who conducted
the LCS reviews during programming. Interviews and focus groups have been
held with the LCS team that directed the process, representatives of the
three organizations who facilitated LCS evaluations in the design phase,
and the designers of the project. The comments generated by the LCS evaluations
are being coded for analysis. Craft foremen from all disciplines are being
debriefed as their scope of work ends to collect data to compare to the
design items identified in prior focus groups. Injury data from the construction
phase will be compared to similar data from earlier projects, and incident
data from the current construction project will be analyzed to link incidents
and injuries to design issues either identified in the LCS process but not
modified or missed by the process.

Examine owner practices as they pertain to construction safety. Evaluate
the effectiveness of owner involvement in construction safety through contractor
selection, contractual requirements, and active participation during the
construction process.
RESEARCH SUMMARY:
Owners of facilities being constructed play a pivotal role in construction
safety. This role begins with selecting a contractor(s) and the contractual
requirements imposed on the contractor. It continues during the construction
phase through the active involvement of the owner in construction safety.
Information on the nature of owner involvement in construction safety was
obtained through personal interviews with owner representatives for over
70 large construction projects. This phase, data collection, is nearing
completion.
The next phase of the research will be to compile various owner practices
employed to promote construction safety. This will reveal the nature of
the variability that exists in owner practices on different projects. The
data will then be examined to identify those practices associated with better
injury rates as defined as the number of OSHA-recordable injuries incurred
per 200,000 hours of worker exposure.
The data analysis will be conducted in the fall of 2002, and the research
report will be completed by the end of spring 2003.

PURPOSE:
Develop a guidance system, or blueprint, comprised of best practices that
contractors can use to link health hazard controls with the planning and
everyday management of construction activities. Assess engineering and work
practice controls to reduce lead and silica exposure and enhance the role
of labor in implementing control programs.
RESEARCH SUMMARY:
Control measures designed to reduce exposures to lead and silica during
infrastructure rehabilitation are often difficult to implement or sustain
successfully. The blueprint project employs a comprehensive three-pronged
approach to improve the integration of health hazard controls into construction
projects by (1) developing, implementing, and assessing blueprint guides;
(2) assessing the de facto role that labor plays in the implementation
of health hazard control programs and enhancing labor's role with a view
toward improving health hazard control integration; and (3) assessing lead
and silica engineering and work practice controls. In developing and assessing
each of these project components, both qualitative and quantitative data
collection methods will be employed, including discussion groups with employers
and workers; interviews with contractors, supervisors, workers, and union
representatives; health hazard control program audits; and industrial hygiene
assessments, including biological monitoring where appropriate. This project
builds upon a growing body of investigations that suggest that the most
effective interventions are those in which workers participate, which stress
the importance of management leadership, and which employ multiple exposure
control strategies— engineering controls, work practices, and respiratory
protection.
The blueprint itself consists of a number of guides that provide practical
guidance to project managers, safety personnel, and workers on day-to-day
management of health hazard control programs. It is designed to be process
oriented, that is, capable of anticipating health hazard control needs within
the phases of a construction project, while being flexible enough to protect
workers during the constant readjustments typical of construction rehabilitation
work.
Each blueprint guide is uniformly structured and provides a brief statement
of its purpose followed by sections on planning and scheduling, identification
of employer and employee roles and responsibilities, and how to implement
and evaluate a "best practice." A resource section contains references,
forms, checklists, and lists of readily available information, useful Web
sites, and supplies and vendors.

PURPOSE:
Develop a software program, SalusCPM, that facilitates the incorporation
of explicit safety-related guidelines into construction schedules.
RESEARCH SUMMARY:
Critical path method (CPM) scheduling software has become a ubiquitous and
indispensable tool in commercial construction project management. Construction
schedules are typically developed around work activities that contribute
to installing the components to complete a structure or facility. These
activities are typically organized sequentially as they occur in the actual
construction process and represent a logical progression of work. For most
commercial construction projects, it is the schedule, more than concerns
for costs or quality, that drives and influences management decisions.
Increasingly, safety has become a major concern on construction projects.
However, CPM schedules typically do not address safety issues or concerns,
despite a high level of interest in promoting safety. Since most injuries
occur during a work activity, it is logical that safety should be emphasized
in conjunction with the activities being planned. Some activities have more
inherent risks than others. Presumably, if safety concerns were linked with
planned activities and explicitly incorporated into schedules, it is more
likely that the activities would be performed with a greater focus on safety.
If widely practiced, this could ultimately result in a significant reduction
in construction-related injuries, illnesses, and deaths.
SalusCPM is a software plug-in that works in tandem with scheduling software,
allowing the user to incorporate a project-specific safety plan directly
into the schedule. There are four components of SalusCPM: Safety Database,
Safety Planner, Safety Integrator, and Safety Manager.
-
The Safety Database component currently contains about 2,500 individual
safety guidelines prepared by safety specialists and organized into checklists.
Each checklist contains a series of guidelines related to a specific type
of construction activity.
-
The Safety Planner allows the user to select, add, delete, and modify
(i.e., customize) the checklist database to suit the safety needs of a particular
construction project.
-
The Safety Integrator works with the CPM scheduling software and allows
the user to insert specific checklists as activities into the CPM schedule.
This resulting schedule can serve as the heart of a site-specific safety
plan, a regulatory requirement for large construction projects.
-
The Safety Manager assists in managing the individual items on the checklist
that arise as work progresses according to the schedule.

PURPOSE:
Determine whether a partnership between third-party safety and health organizations
and construction contractors can reduce fall hazards at construction sites
through implementation of a fall hazard management program that includes
training, safety committees, inspections, accountability, and third-party
oversight.
RESEARCH SUMMARY:
Falls are the leading cause of fatal-ities and a major cause of injury in
construction work. While construction workers represent 5% of the nation's
workforce, they account for 49.6% of fall fatalities. In West Virginia,
the construction industry accounts for more than a third of all occupational
falls, both fatal and nonfatal.
A partnership between West Virginia University (WVU) (and more recently
St. Paul Insurance and Construction Safety Council) and construction contractors
has been established in which contractors obtain "Fall-Safe" status by implementing
a fall hazard management system developed by the university. Important elements
of the system are development of company policies, training of supervisors
and workers, development of site-specific fall hazard control plans, development
of communication and accountability systems on-site to manage fall hazards,
and regular site inspections by contractor personnel. Contractors maintain
Fall-Safe status by achieving a minimum score on site program and site fall
hazard control audits. The audits also act as a service to the contractor
by providing feedback to the safety director to further assist in the control
of fall hazards on the jobsite.
The research methodology employs a quasi-experimental model that compares
outcome measures in an intervention group with measures in a control group.
These measures include surveys of employers, supervisors, and employees;
audits of construction site fall prevention plans and site fall hazard control
efforts; and analyses of fall-related claims to workers' compensation systems.
Statistical analysis of the data collected from 16 contractors (10 intervention,
6 control) in a pilot phase of the research indicates that the intervention
group of contractors has shown more improvement in site program and site
hazard control scores than the control group. Results also indicate that
scores for site hazard control audits can be associated with scores on the
site program audit.
An unexpected result of the research suggests that a less-intensive intervention
such as a user-friendly computerized auditing tool might also lead to changes
in contractor safety performance. Given that WVU estimates it will cost
approximately $10,000 per year for a contractor to implement the Fall-Safe
program (internal costs and fees to the third-party partner), this finding
is particularly important.
The study has now been expanded to include 40 additional contractors and
the two participating partners of the St. Paul Insurance and Construction
Safety Council. The current study tests whether the intervention can succeed
when implemented by other third-party organizations in other regions of
the country. The higher number of participants will permit the use of workers'
compensation injury claims data as an outcome measure.

PURPOSE:
Introduce technical and organizational interventions into the construction
work environment and evaluate the effective-ness of these interventions
in reducing exposures among concrete workers to respiratory hazards and
musculoskeletal injuries.
RESEARCH SUMMARY:
Partnering with area construction unions and contractors and joint labor-management
training programs has resulted in participatory research activities carried
out with workers at regional training centers and on construction sites.
Three studies were conducted.
- Hardhat Ergonomics was a training program in which popular education
methods were used to facilitate classes where workers conducted ergonomic
job analyses, identified key agents of change, and role-played strategies
for making changes at their workplaces.
-
Health Trak was a joint labor/management participatory action research
project. Small groups of workers and frontline supervisors met weekly over
a 2-month period to identify current hazards on their site and design and
propose solutions.
-
The Boston-Area Health and Safety for Women in Construction
(HASWIC) Research Circle was a standing focus group of tradeswomen
who drew on their extensive experience to evaluate working conditions
and analyze the roles of workers, unions, contractors, and government
in making and impeding changes.
Each of these activities used a mix of qualitative and quantitative participatory
research methods to examine the role of change in the construction work
envi-ronment. The resulting exchange of information demonstrated that workers
are able to analyze their jobs and design interventions to reduce hazards,
but are hindered in making their proposed changes by organizational factors.
Four contexts that influence intervention effectiveness have been identified:
organizational context in which the intervention is being introduced, attributes
of the intervention itself, the process by which the intervention is introduced,
and approaches to health and safety issues by participating trade unions.
To assess each of these contexts, approximately 50 factors influencing inter-vention
effectiveness have been identified, defined, and organized into a matrix
describing the specific information sought, source of that information,
time (pre- or post-intervention), and method of data collection. This matrix
will be used to develop specific protocols for collecting both quantitative
and qualitative data for a working model of the effectiveness of intervention
studies.
