Training on the hazards of concrete and cement, such as silicosis, and ways to protect yourself – includes questions for discussion and a sign-off form. Part of a collection. Click on the 'collection' button to access the other items.
|These tailgate/toolbox talks were developed for use under California OSHA regulations. The complete set is available from the Labor Occupational Health Program at UC Berkeley. For ordering information, visit the website (www.lohp.org) The American Conference of Government Industrial Hygienists (ACGIH) has adapted these talks to apply to federal OSHA regulations.

Before you begin
- Does this topic
relate to the work the crew is doing? If not, choose another topic.
- Has the crew completed basic Hazard Communication training? It will help them understand this topic.
- Did you read
this Training Guide and fill in the blanks where the
appears? (To find the information you need, look over the Safety Walkaround
Checklist for this topic.)
- Did you bring labeled containers and Material Safety Data Sheets (MSDSs) for a few of the adhesive and resin products used on the site?
and concrete are so common on a construction site that you probably don’t
think much about them. They’re just part of the job. But did you
know that cement and concrete dust can cause lung damage? Did you know
that you can get an allergic reaction from skin contact with cement? Without
protection, cement and concrete can be bad news.
You or a crew member may want to add a personal story about cement or concrete hazards.
Next discuss with the crew where cement and concrete work will be done at this particular job site:
ASK THE CREW THESE QUESTIONS:
After each question, give the crew time to suggest possible answers. Use the information following each question to add points that no one mentions.
in cement that can be harmful?
- Different cements have different ingredients. Many of them contain substances that can be hazardous, like silica, lime, gypsum, nickel, cobalt, and chromium compounds.
- Chronic bronchitis.
from the crystalline silica (quartz) used in many cements.
- Cancer— from the small amounts of chromium compounds found in some cements. (Scientists are still debating whether the silica in cement dust may also cause cancer.)
3. What are the
symptoms of silicosis?
silicosis can occur after a few weeks of very high exposure (for example,
in sandblasters). Symptoms are shortness of breath, coughing, fever,
and weight loss.
silicosis is rarely seen in workers with less than ten years of exposure.
It permanently damages your lungs.
- Silicosis also increases your chance of getting tuberculosis.
4. Is it dangerous
if you get cement dust or wet cement on your skin?
- Yes. Getting
cement dust or wet cement on your skin can cause burns, rashes,
other kinds of skin irritation. Lime, found in most cements, is often
- Some workers
slowly become allergic to cement if they have skin contact with
it over a
long period of time.
- Cement dust and wet cement can also irritate your eyes.
5. How can you
find out the ingredients in the particular cement you’re using?
- If you can, get
a bag and check the label. You may find a list of ingredients,
a safety warning, or both.
- Read the Material
Safety Data Sheet (MSDS) for the product. MSDSs are required by
law. They’ll tell you the ingredients and possible health hazards.
Everyone working on the site has a right to see MSDSs.
- When you work with cement you often use other chemicals too—form oils, curing agents, bond breakers, and retardants. Remember to check their MSDSs.
On this job, you can get MSDSs from-
Give the name and location of the person to see:____________
Let's look at some MSDSs for cement products we use on this job.
Show the crew the sample MSDSs you brought to the meeting. Explain them briefly.
(MSDSs are covered in more detail during basic Hazard Communication training, which everyone on the crew should already have completed.)
What about concrete? Can concrete dust also harm you?
- Yes. When concrete is cut, drilled, or broken up, the dust has all the same hazards as the dust from new cement. The only difference is that, since it isn’t a new product, there will be no label or MSDS to check. So play it safe.
7. How can you
protect yourself from breathing cement and concrete dust?
- Stay out of dusty
areas if you can.
- Wet down the
work to keep dust out of the air.
- Use power tools
with HEPA filters when you’re cutting or drilling concrete.
- Use a special
HEPA vacuum to clean up dust, not dry sweeping.
- Wear a respirator
with HEPA cartridges if there’s a lot of dust in the air.
(Respirators are covered in more detail in a separate Training Guide.)
On this job, the precautions we will be taking are:___________
8. What are some
things you can do to protect your skin and eyes from cement?
- Don’t get
wet or dry cement on your skin or in your eyes. If you do, immediately
wash it off with a lot of water.
- Wear goggles,
or safety glasses with side shields, to protect yourself from splashes.
- Wear boots
and other protective clothing if necessary.
- Wear gloves.
Use a type which are impermeable— the cement can’t get through
them. Leather or cloth work gloves won’t protect you.
- The company is required to supply the personal protective equipment (PPE) you need and train you in its use. (PPE is covered in more detail in a separate Training Guide.)
On this job, the protective equipment you'll need is:___________
Explain: Most of the safety measures we’ve talked about are required by Cal/OSHA. We have to take these precautions—it’s the law. For example, Cal/OSHA says we must make sure no one on the site is exposed to more than 10 milligrams of cement dust per cubic meter of air, averaged over an 8-hour shift. This is called the permissible exposure limit (PEL) for cement dust. But there are lower limits if the dust is very fine and easy to breathe deep into the lungs. The limit is also lower if the dust contains toxic substances like chromium. I have a Checklist of the Cal/OSHA regulations on cement and concrete. If you’d like to know more, see me after the meeting.
(Only if applicable.) Besides the Cal/OSHA regulations, we have some additional company rules to prevent back injuries.
Discuss company rules:_______________________________
COMMENTS FROM THE CREW
Ask: Do you have any other concerns about cement or concrete? Do you see any problems on our job? (Let the steward answer first, if there is one.)
What about other jobs you’ve worked on? Have you had any experience with cement or concrete that might help us work safer on this job?
GENERAL SAFETY DISCUSSION
This is a time to discuss all safety concerns, not just today's topic. Keep your notes on this page before, during and after the safety meeting.
Are you aware of any hazards from other crews? Point out any hazards other crews are creating that this crew should know about. Tell the crew what you intend to do about those hazards.
Do we have any old business? Discuss past issues/problems. Report progress of investigations and action taken.
Any new business?
Any accidents/near misses/complaints? Discuss accidents, near misses,
and complaints that have happened since the last safety meting. Also recognize
the safety contributions made by members of the crew.
Please remember, we want to hear from you about any health and safety issues that come up. If we don't know about problems, we can't take action to fix them.
To complete the training session:
- Circulate Sign-Off
- Assign one
or more crew member(s) to help with next safety meeting.
- Refer action items for follow-up. (Use the sample Hazard Report Form in the Reference Section of this binder, or your company’s own form.)
