Sneezing, coughing, sore throat. Common causes:
Cement, fiberglass, wood dust, solvents, welding fumes, smoke (including tobacco).
  CHEST & LUNGS
Wheezing, coughing, shortness of breath, lung cancer.
Common causes: Cement, fiberglass, wood dust, welding fumes, smoke (including tobacco), solvents.
SKIN
Redness, dryness, rash, itching, skin cancer.
Common causes:
Solvents, cement, fiberglass, wood dust.
  STOMACH
Nausea, vomiting, stomach ache.
Common causes:
Some wood dust, solvents, long-term lead exposure, job stress.
NERVOUS SYSTEM Nervousness, irritability, sleeplessness, tremors. Common causes:
Long-term solvent exposure, longterm lead exposure, job stress.
  REPRODUCTIVE SYSTEM
For men: low sperm count, damage to sperm.
For women: irregularities in menstruation, miscarriage, damage to egg or fetus. Common causes:
Lead, toluene, some other solvents.




How Do I Know If the Construction Job I’m Working on Is Hazardous?

 To figure out what the hazards of a particular construction job may be, ask these questions and check the chart on the following pages. The chart also suggests important control measures that can be taken to protect workers.


1. Is there a lot of dust in the air?
    The air on construction sites, especially during demolition work, can contain asbestos, silica, cement dust, fiberglass and wood dust. Most of these dusts can irritate your eyes, nose and lungs. Some can cause bronchitis, asthma and even cancer.
2. Do any of the materials you work with contain solvents?
    Varnishes, wood sealers, paints, thinners, adhesives and many other construction materials contain solvents. They can get into your body through your skin or when you breathe the vapors. Solvents can give you headaches and make you dizzy. If you work with them for many years, they may damage your liver or nervous system.
3. Do you use any materials that contain polyurethane or epoxy resins?
    Many construction materials — like adhesives, sealants, waterproofing agents, floor and wall coverings — are made up of isocyanate (the raw material for polyurethane) or epoxy resin systems. The chemicals in these systems can get into your body through your skin, or when you breathe the mists or vapors. They can irritate your nose, eyes, throat and lungs. Some people may develop an allergic reaction, similar to asthma.
 4 What are other trades doing nearby?
    In construction work, someone else’s work may produce welding fumes, chemical vapors, asphalt smoke or other toxic hazards. These can affect everyone in the vicinity. Be aware of what other trades are doing, and protect yourself.
5 Are you exposed to cigarette smoke?
    If you or someone else smokes on the job, you’re being exposed to many more toxic substances. Cigarette smoke contains over 4,000 chemicals.

Health Effects
CADMIUM, CHROMIUM, COPPER, ZINC, MAGNESIUM Welding; drilling, cutting and sawing pipes; scraping rust or coatings. Short-term: Metal dusts can be irritating to skin, nose, eyes and lungs. Effects of fumes differ depending on metal (see MSDS). Some metals (such as zinc, copper, and magnesium) cause metal fume fever (flu-like symptoms with fever, nausea, chills and muscular aches and pains).
Long-term: Depends on metal (see MSDS). Cadmium and chromium can cause cancer.
LEAD Cable splicing, demolition, remodeling, painting, pipefitting, plumbing, roofing, sheetmetal, iron work, welding on lead or surfaces with lead paint or coatings; brass fixtures may release lead. Short-term: Effects are very rare. If exposure is high, symptoms similar to long-term effects may occur.
Long-term: Damage to brain and nerves (tremors, muscular weakness, lack of coordination), damage to reproductive systems (men and women), stomach problems, anemia, damage to kidneys.

          CONTROLS FOR METALS
METAL DUSTS Wear the correct respirator if required (not a paper dust mask).

Vacuum or wipe off surfaces using wet mop or rags. (Avoid sweeping and blowing away dusts to clear surfaces.)

Keep work materials wet where possible when sanding, grinding, sawing, etc.

Don’t drink, eat or smoke in work area.

Wash hands before eating and before breaks.

Change clothing and, where possible, shower before going home.

Use local exhaust ventilation if not working in an open area.

Isolate dusty operations such as sawing and sanding to reduce worker exposure.
METAL FUMES Avoid welding on toxic metals or coatings; brush or scrub off coatings first.

Natural ventilation is often adequate in open areas.

Position yourself so that fumes don’t blow into your face.

Use local exhaust ventilation in indoor areas or confined spaces.

Wear the correct respirator when ventilation or other controls are not possible.

Lead: Shower and change clothes to avoid bringing lead home to your family.

Construction Hazards : Solvents

SOLVENTS
Special Hazrds
Source
BENZENE Causes leukemia. These solvents may be found in:

Varnishes
Finishes
Wood sealers
Thinners
Paints
Adhesives
Cleaning and degreasing
solutions
Other products
METHYLENE CHLORIDE May cause cancer.
TOLUENE Liver and kidney damage at high levels. May cause birth defects.
TRICHLORO-ETHYLENE Liver damage. May cause cancer.

Health Effects
CONTROLS FOR SOLVENTS
Most solvents you work with, including acetone, TCE or other degreasers, affect your health in similar ways:

Short-term: Most organic solvents affect the brain the same way drinking alcohol does. Overexposure causes symptoms resembling drunkenness, including headaches, "feeling high," nausea, dizziness, and at high levels, loss of coordination. Other short-term health effects are eye, nose and throat irritation, and skin rash.
Long-term: Repeated, frequent overexposure over months or years may cause long-lasting damage to the central nervous system (the brain and nerves).
Where possible, substitute materials that are less toxic.

Use ventilation to remove vapors.

Wear the correct respirator (refer to MSDS).

Wear proper protective clothing, correct gloves, goggles, face shields.

No smoking. No open flame nearby. Vapors can build up quickly and become extremely dangerous in confined spaces.

Follow OSHA confined space entry procedures where required. (These include pretesting atmosphere before entry; mechanical ventilation of space; respirators; rescue person.) Many fatalities occur in confined spaces.

Secondhand Smoke Facts

 You may be smoking, whether or not you ever put a cigarette in your mouth. If you work where people smoke, you may inhale the equivalent of a pack a day of other people's smoke. Here are some facts about secondhand smoke.

  • Secondhand smoke contains 4,000 chemicals, including over 50 known carcinogens. Smoke from the tip of a cigarette has 20 times the carcinogens as smoke inhaled by a smoker.
  • Secondhand smoke is the third leading preventable cause of death in America, killing over 53,000 nonsmokers every year. 50,000 of these deaths are from heart disease. 3,000 are from lung cancer.
  • The U.S. Environmental Protection Agency (EPA) has classified secondhand smoke as a Group A carcinogen — a substance known to cause cancer in humans. There is no safe level of exposure to Group A carcinogens, which also include asbestos and benzene.
  • If you breathe secondhand smoke, your health risk is higher if you’re also exposed to toxic chemicals. For example, tobacco smoke contains hydrogen cyanide, a chemical that paralyzes the cilia (tiny filtering hairs) in your lungs. That makes it harder for your lungs to filter out other toxics.
  • Tobacco smoke adds harmful chemicals to those already in the work environment, increasing the total amount you’re exposed to and increasing the risk of cancer, heart disease, asthma, respiratory problems and other diseases.
  • Breathing secondhand smoke means more chemicals for your body to handle. For example,  welding on the construction site produces carbon monoxide. Tobacco smoke also contains carbon monoxide, so you are getting a much larger dose. Long-term exposure to carbon monoxide weakens the heart.
  • When the chemicals in tobacco smoke combine with certain other cancer-causing substances, such as asbestos, the combination greatly increases the risk of lung cancer.
  • Secondhand smoke hurts kids by causing ear infections and respiratory problems such as asthma. It also has been linked to Sudden Infant Death Syndrome (SIDS).
  • California law bans smoking in indoor workplaces to protect workers from secondhand smoke. Some employers and some local laws ban smoking in outdoor areas, too.

    The Odds Against Tobacco Users’ Health

    SMOKING

    Smoking causes:
    • 90% of lung cancer deaths
    • 80% of emphysema and chronic bronchitis deaths
    • 30% of cancer deaths
    • 20% of heart disease deaths

    Each year, over 400,000 Americans die prematurely because of smoking. Smoking kills more Americans each year than alcohol, cocaine, crack, heroin, homicide, suicide, car crashes, fires and AIDS combined. Smoking also causes impotence.

    CHEWING TOBACCO

    Smokeless tobacco is not a safe alternative to smoking. Chewing tobacco causes cancer of the mouth, larynx and esophagus. Long-term “chew” users are 50 times more likely to get cancer of the cheek and gum than non-users. Chewing tobacco contains arsenic, cyanide, lead and benzene. It also contains fiberglass and dirt, which cause abrasions on the skin so the tobacco can enter the bloodstream more readily. Chewers get three times as much nicotine as smokers. It can be even harder to quit chew than cigarettes.

    QUITTING

    In the last 25 years, nearly half of all American adults who ever smoked have quit. Millions and millions of people have quit. But most smokers try several times before they quit permanently. Nicotine is a highly addictive drug. The reason people use tobacco is to satisfy their addiction to nicotine. Quitting smoking or chewing tobacco can be at least as difficult as quitting cocaine or heroin.

    Combining Tobacco Smoke & Workplace Toxics

    When tobacco smoke combines with other toxics in the workplace, there is extra danger to your health.

    1. Some combinations ADD TO the odds against your health.
      If you smoke, your lungs aren’t as good at keeping other chemicals out. Tobacco smoke damages your lungs’ ability to protect themselves against other toxic substances you may inhale.

      LUNGS: The odds of construction workers getting bronchitis, asthma or other lung diseases are high because you may work with asphalt, coal tar, treated wood and other lung hazards. Tobacco smoke makes it harder for your lungs to get rid of those chemicals.

      Smoking also means more chemicals for your body to handle. Your body may be able to stand small amounts of some chemicals, but not larger amounts. Tobacco smoke can cause higher levels of the same harmful chemicals you’re already exposed to on the job. It also adds other harmful chemicals.

      HEART: Welding on a construction site produces carbon monoxide. Tobacco smoke also contains carbon monoxide. You may not feel sick with a 5 to 10% level of carbon monoxide in your blood. But a 10 to 20% level can cause headaches and make you abnormally tired. Long-term exposure to carbon monoxide weakens the heart.
    2. Some combinations MULTIPLY the odds against your health.
      Some toxics can work together inside your body to strengthen each other’s power to cause disease. This is called synergy. For example, the odds against your health multiply when you combine tobacco smoke with asbestos:



      Scientists suspect that tobacco smoke and the ferric oxide in welding fumes also combine to multiply your risk of getting cancer.
    3. If you smoke, you’re more likely to have contact with workplace chemicals.
      Dangerous chemicals can enter your body when you breathe them, swallow them, or get them on your skin. The dust from some chemicals, like lead or cadmium, may collect on your cigarettes. Then, when you put a cigarette to your lips and inhale, you are not only taking in tobacco smoke, you are also taking in extra toxics.
    4. Smoking on the job increases the risk of fire and explosion.

    5. Smokers are more likely to have job injuries because they can be distracted by eye irritation, coughing or having only one hand free.
