Methods for reducing heat effect on workers
include:
-use of mechanical equipment to reduce physical
labor requirements,
- scheduling hot work for the cooler part of the day,
-use of sun shields, providing cool rest areas
[optimum temperatures about 77°F (25°C)],
-providing a water and salt supply easily accessible
to workers, and
-use of proper hot-weather clothing.

- 3. Construction Hazards Potential hazardsfor workers in construction Falls (from heights) Trench collapse Scaffold collapse Electric shock Failure to use proper personal protective equipment Repe t i t i
- 4. OSHA Standards Scaffolding Fall Protection Ladders Stairways OSHAMost Frequently Cited Standards that must be Checked include: Head Protection Cranes Trenching
- 5. OSHA Standards Scaffolding Hazard - Fallhazards - Collapse hazards Solutions -Scaffold must be sound, rigid and sufficient to carry its own weight plus four times the maximum intended load. - Unstable objects, such as barrels or boxes must not be used to support scaffolds or planks.
- 6. OSHA Standards Scaffolding Solution s - Scaffoldmust not be erected except under the supervision of a competent person. -Scaffold must be equipped with guardrails -Scaffolds must be at least 10 feet from electric power lines at all times.
- 7. OSHA Standards Fall Protection Hazard Eachyear, falls consistently account for the greatest number of fatalities in the construction industry. Solutions Consider using aerial lifts or elevated platforms Erect guardrail systems with toe boards and warning lines
- 8. OSHA Standards Fall Protection Solution s Coverfloor holes Use safety net systems Use personal fall arrest systems (body harnesses)
- 9. OSHA Standards Ladders Hazard Ladders andstairways are another source of injuries and fatalities among construction workers. Solutions Use the correct ladder for the task. Have a competent person visually inspect a ladder before use for any defects.
- 10. OSHA Standards Ladders Solution s Make surethat ladders are long enough to safely reach the work area. Never load ladders beyond the maximum intended load Avoid using ladders with metallic components near electrical work
- 11. OSHA Standards Stairways Hazard Slips, tripsand falls on stairways area major source of injuries and fatalities among construction workers. Solutions Stairway treads and walkways must be free of dangerous objects, debris and materials. Stairways having four or more risers or rising more than 30 inches must have at least one handrail.
- 12. OSHA Standards Trenching Hazard Trench collapsescause dozens of fatalities and hundreds of injuries each year. Solutions Never enter an unprotected trench. Always use a protective system for trenches 5 feet deep or greater.
- 13. OSHA Standards Trenching Solution s Employ aregistered professional engineer to design a protective system for trenches 20 feet deep or greater. Always provide a way to exit a trench—such as a ladder, stairway Make sure that trenches are inspected by a competent person prior to entry and after any hazard-increasing event
- 14. OSHA Standards Cranes Hazard Significant andserious injuries may occur if cranes are not inspected before use and if they are not used properly. Solutions Check all crane controls to insure proper operation before use. Inspect wire rope, chains and hook for any damage.
- 15. OSHA Standards Cranes Solution s Know theweight of the load that the crane is to lift. Ensure that the load does not exceed the crane’s rated capacity. Raise the load a few inches to verify balance and the effectiveness of the brake system.
- 16. OSHA Standards Cranes Solution s Do notmove a load over workers. Barricade accessible areas within the crane’s swing radius. Watch for overhead electrical distribution and transmission lines and maintain a safe working clearance of at least 10 feet from energized electrical lines.
- 17. OSHA Standards Head Protection Hazar d Serioushead injuries can result from blows to the head. Solution s Be sure that workers wear hard hats

- 19. Environmental Health inConstruction Noise Dust Radiation Toxic Materials Heat Cold Cab enclosures can be used on construction equipment to protect equipment operators from equipment noise. The use of such enclosures has necessitated improved equipment instrumentation to enable the operator to determine whether the machine is operating properly without depending on the sound of the equipment's operation.
- 20. Environmental Health inConstruction Noise Dust Radiation Toxic Materials Heat Cold Although the use of operator enclosures permits an improved operator environment, it also creates a safety hazard, because it is difficult for workers outside the enclosures to communicate with the equipment operator. As a result, increased attention must be given to the use of guides, backup alarms, and hand signals if accidents are to be avoided.
- 21. Environmental Health inConstruction Noise Dust Radiation Toxic Materials In addition to creating a safety hazard due to loss of visibility, dust may be responsible for a number of lung diseases. Silica dust and asbestos dust are particularly dangerous and produce specific lung diseases (asbestosis and silicosis). Heat Cold
- 22. Environmental Health inConstruction Noise Dust Radiation Toxic Materials Asbestos dust has also been found to be a cancer- producing agent. As a result, OSHA safety and health standards limit the concentration of dust to which workers may be exposed. The allowable concentration of asbestos particles is, as you might expect, quite low. Heat Cold
- 23. Environmental Health inConstruction Noise Dust Radiation Toxic Materials Ionizing radiation is produced by X-ray equipment and by radioactive material. Such radiation may be present on the construction site when X-raying welds, measuring soil density, or performing nondestructive materials testing. Heat Cold
- 24. Environmental Health inConstruction Noise Dust Radiation Toxic Materials only well-trained employees should be permitted to operate such equipment. Workers must be provided anti laser eye protection when working in areas having a potential exposure to laser light output greater than 5 mW. Heat Cold
- 25. Environmental Health inConstruction Noise Dust Radiation Toxic Materials Construction workers may accidentally encounter toxic materials at any time, particularly on reconstruction projects. Every effort must be made to locate and properly protect utility lines during excavation operations. Heat Cold
- 26. Environmental Health inConstruction Noise Dust Radiation Toxic Materials The air in a work area should be tested whenever an oxygen deficiency or toxic gas is likely to be encountered. Specific safety procedures and protective equipment should be provided if hazardous liquids or solids are likely to be encountered. Heat Cold
- 27. Environmental Health inConstruction Noise Dust Radiation Toxic Materials Construction workers are often required to work under high-temperature conditions. Fortunately, the human body will acclimate itself to high- temperature conditions within a period of 7 to 10 days. Heat Cold
- 28. Environmental Health inConstruction Noise Dust Radiation Toxic Materials serious heat illness may result when workers are not properly acclimated and protected. Medical effects range from fatal heat stroke to minor heat fatigue. It is particularly important to health that the body's water and salt levels be maintained. Heat Cold
- 29. Environmental Health inConstruction Noise Dust Radiation Toxic Materials Methods for reducing heat effect on workers include: -use of mechanical equipment to reduce physical labor requirements, - scheduling hot work for the cooler part of the day, -use of sun shields, providing cool rest areas [optimum temperatures about 77°F (25°C)], -providing a water and salt supply easily accessible to workers, and -use of proper hot-weather clothing. Heat Cold
- 30. Environmental Health inConstruction Noise Dust Radiation Toxic Materials Heat Cold Medical effects of cold include: -frostbite, -trench foot, -general hypothermia (reduction of the core body temperature). General hypothermia is usually fatal when the body core temperature drops below 65°F (18°C).
- 31. Environmental Health inConstruction Noise Dust Radiation Toxic Materials Heat Cold The major requirement for successful cold- weather construction appears to be the provision of adequate clothing and warming areas. The use of bulky cold-weather clothing, however, reduces manual dexterity and may increase the possibility of accidents.
