  • We are looking at the occupational health risks related to construction work, specifically regarding the role of a GENERAL CONTRACTOR.
  • S
  • Health 350 General Contractor

    1. 1. “ What is your occupation?” 1700 - diseases of metal diggers… noting their afflictions came from inhaling noxious gases… … dusts or from disorderly motions & improper postures of the body
    2. 3. A General Contractor is responsible for: <ul><li>Hiring skilled, knowledgeable workers with training in workplace safety </li></ul><ul><li>Ensuring the use of safe tools by workers </li></ul><ul><li>Ensuring proper safety equipment is worn at all times on site </li></ul><ul><li>Creating a safe work environment </li></ul>
    3. 4. Skilled Workers <ul><li>An educated worker is more aware of workplace hazards </li></ul><ul><li>Injuries can be avoided when workers are aware of the risks and how to avoid them </li></ul><ul><li>Safety training increases likelihood of taking precautions to avoid workplace injury </li></ul>
    4. 5. OSHA standards for PPE <ul><li>“ Employer shall provide a training program for each employee who might be exposed to hazards.” </li></ul><ul><li>Employer shall ensure that each employee has been trained by a competent, qualified expert in the following areas: </li></ul><ul><ul><li>The nature of fall hazards </li></ul></ul><ul><ul><li>Correct procedures for erecting, maintaining, disassembling and inspecting the protection systems to be used </li></ul></ul><ul><li>This expert should be a qualified occupational health and safety professional </li></ul>
    5. 6. Education <ul><li>Undergrad or graduate degree programs in building construction technology, construction management, architecture or engineering programs include safety training </li></ul><ul><li>WHMIS and MSDS </li></ul><ul><li>training is essential </li></ul><ul><li>for all hired workers </li></ul>
    6. 7. Safety Tools and Maintenance <ul><li>Cordless power tools </li></ul><ul><ul><li>Eliminate risk of electrical burns & shock </li></ul></ul><ul><ul><li>Eliminate tripping hazards & injuries </li></ul></ul><ul><li>Quality tools </li></ul><ul><ul><li>Ergonomic design to reduce vibration </li></ul></ul><ul><ul><li>Lifts/cranes should be used for heavy lifting </li></ul></ul><ul><li>Proper maintenance of tools </li></ul><ul><ul><li>Ensure proper function of tools before beginning any job </li></ul></ul>
    7. 8. OSH Division <ul><li>“ Musculoskeletal (muscle joint and bone) injuries are the most common injury problem in the construction industry.” </li></ul><ul><li>They account for over 1/3 of all lost workday injuries and produce about 1/2 of all compensation claims </li></ul><ul><li>Ergonomics means </li></ul><ul><ul><li>finding ways to make work easier so workers can work smarter, not harder! </li></ul></ul><ul><ul><li>Asking experienced workers for their ideas on how to do the work </li></ul></ul><ul><ul><li>More productive workers since workers are less often fatigued or hurt </li></ul></ul>
    8. 9. Ergonomics <ul><li>Better, ergonomically designed tools are </li></ul><ul><ul><li>Lighter weight </li></ul></ul><ul><ul><li>Require less force to operate </li></ul></ul><ul><ul><li>Fit the hand better </li></ul></ul><ul><ul><li>More comfortable to use </li></ul></ul><ul><li>Use carts or dollies, handles when carrying loads </li></ul><ul><li>Wear protective equipment (knee/shoulder pads) to reduce contact stresses of kneeling work or carrying materials </li></ul><ul><li>Stretching programs before beginning work </li></ul>
    9. 10. Proper Safety Equipment <ul><li>Hard hats (risk of head injury from falling objects) </li></ul><ul><li>Gloves (risk of chemical burns,cuts etc.) </li></ul><ul><li>Safety boots and jacket </li></ul><ul><li>Masks/respirators (inhalable/respirable dust) </li></ul><ul><li>Ear plugs/ear muffs (noise exposure) </li></ul><ul><li>Eye protection/goggles </li></ul><ul><li>Harnesses (meeting Regulatory standards) </li></ul>
    10. 11. OSHA Standards Respiratory Protection <ul><li>“ All PPE shall be of safe design and construction for the work to be performed.” </li></ul><ul><li>“ A respirator shall be provided where there is exposure to harmful dusts, fogs, fumes, gases, mists, smokes, sprays or vapours” </li></ul><ul><ul><li>Use of respirators should be secondary to the primary objective, which is to prevent atmospheric contamination </li></ul></ul><ul><ul><li>e.g., Air purifying respirator to remove specific air contaminants by passing ambient air through air purifying element </li></ul></ul>
    11. 12. Safe Work Environment <ul><li>Use of rails (meeting regulatory standards) to prevent falls </li></ul><ul><li>Safe working/weather conditions </li></ul><ul><li>Noise exposure does not exceed safe levels </li></ul><ul><li>Fume and dusts levels as low as possible (proper ventilation) </li></ul><ul><li>Work site free of hazards and spills (proper clean-up procedures) </li></ul><ul><li>Access to Material Safety Data Sheets </li></ul><ul><li>First aid kits </li></ul>
    12. 13. OSHA <ul><li>“ Wherever it is not feasible to reduce noise levels or exposures, ear protective devices shall be provided and used.” </li></ul><ul><li>Ear protective devices inserted in ear should be properly fitted </li></ul>
    13. 14. OSH <ul><li>Maintain safe noise environment </li></ul><ul><ul><ul><ul><ul><li>e.g., lubrication of equipment to reduce grinding noises </li></ul></ul></ul></ul></ul><ul><ul><ul><ul><ul><li>Buy quieter machines, increased cost worth increased worker safety </li></ul></ul></ul></ul></ul>
    14. 15. Take Home Messages <ul><li>There is literature available on proper procedures and there are colleges that teach proper safety procedures </li></ul><ul><li>Hard physical labour cannot fully be eliminated with proper equipment, but risks can be minimized </li></ul><ul><li>Noise and inhalation exposures still a concern, despite the best precautionary measures </li></ul><ul><li>The combined efforts of employer and workers contribute to better work satisfaction and productivity </li></ul>
