Final answer:
Different job functions can lead to different levels of exposure to health hazards for construction workers. Occupational Safety and Health Administration (OSHA) standards enforce measures to protect construction workers from various hazards, including falls, infectious diseases, exposure to harmful chemicals, and dangerous machines.
Step-by-step explanation:
Different job functions can lead to different levels of exposure. Most occupational exposures are caused by absorption through exposed skin such as the face, hands, forearms, neck, and chest. This exposure is sometimes enhanced by inhalation in settings including spraying operations in greenhouses and other closed environments, tractor cabs, and the operation of rotary fan mist sprayers.
OSHA's current Construction, General Industry, Maritime and Agriculture standards are designed to protect workers from a wide range of serious hazards. Examples of OSHA standards include requirements for employers to: provide fall protection such as a safety harness/line or guardrails; prevent trenching cave-ins; prevent exposure to some infectious diseases; ensure the safety of workers who enter confined spaces; prevent exposure to harmful chemicals; put guards on dangerous machines; provide respirators or other safety equipment; and provide training for certain dangerous jobs in a language and vocabulary workers can understand. Employers must also comply with the General Duty Clause of the OSH Act. This clause requires employers to keep their workplaces free of serious recognized hazards and is generally cited when no specific OSHA standard applies to the hazard.
