• Biological hazards: Exposure to bacteria, viruses or other pathogens on the site can lead to illness.

OSHA Standards and Guidelines

OSHA has a range of safety regulations specific to construction, designed to minimize site hazards. Key standards include:

• Fall Protection (29 CFR 1926.501): Requires that all workers at heights be provided with appropriate fall protection systems.
• Hazard Communication (29 CFR 1910.1200): Ensures that workers are informed about hazardous chemicals on-site and how to handle them safely.
• Personal Protective Equipment (PPE) (29 CFR 1926.28): Mandates the use of hard hats, gloves, goggles and other protective gear to reduce injury risk.

Compliance with OSHA regulations is vital to avoid penalties and reduce serious injury risks. Regular training ensures workers understand and apply these standards effectively through hands-on demonstrations, safety drills and refresher courses.

Risk Assessment

A thorough risk assessment is essential for preventing accidents on construction sites. Here's how to do it:

• Identify hazards: Walk the site to spot dangers like uneven surfaces and unguarded machinery.
• Categorize hazards: Rank each hazard by severity and likelihood of harm to prioritize risks.
• Use detection tools: Leverage checklists and site inspections to regularly monitor work conditions.

Top 10 Hazards on Construction Sites

Falls from Heights

Falls from heights are a leading cause of injuries and fatalities on construction sites, often occurring on scaffolding, ladders or near unprotected edges.

OSHA Standards mandate fall protection systems for workers at heights above six feet (29 CFR 1926.501) and set requirements for scaffolding integrity (29 CFR 1926.451).

Prevention involves installing guardrails, using personal fall arrest systems, employing safety nets and providing fall protection training for workers.

Struck-By Incidents

Struck-by hazards occur when workers are hit by falling objects, vehicles or machinery, often due to unsecured materials or poor visibility.

• OSHA Standards require training to prevent struck-by incidents (29 CFR 1926.20 and 1926.21) and safety measures for crane operations (29 CFR 1926.1428).
• Prevention includes using PPE, enforcing machinery protocols, installing warning signage and employing spotters to keep operators aware of nearby workers.

Electrocution

Electrical hazards occur when workers encounter live wires, faulty equipment or improper grounding, posing serious risks on construction sites. Electrocution is a fatal shock, but contact with electrical current can cause other injuries, including severe burns and deadly arc flashes.

• OSHA Standards require safe work practices for electrical installations (29 CFR 1926.400) and guidelines for electrical safety (29 CFR 1926.416).
• Prevention includes using insulated tools, ensuring proper grounding of equipment, providing training on electrical safety and implementing lockout/tagout procedures during maintenance.

Caught-In/Between Hazards

Caught-in/between hazards occur when workers are trapped or crushed by machinery, equipment or materials, which are all common risks on construction sites.

• OSHA Standards require safety measures to protect workers from moving parts and equipment (29 CFR 1926.300) and provide guidelines for machinery operation (29 CFR 1926.602).
• Prevention involves using proper machine guarding, training workers on safe operating procedures, ensuring equipment is properly maintained and using lockout/tagout practices during maintenance.

Hazardous Materials

Hazardous materials pose risks to workers' health and safety through exposure to chemicals, toxic substances or flammable materials on construction sites.

• OSHA Standards require proper labeling and communication of hazardous substances (29 CFR 1910.1200) and guidelines for handling and storing chemicals (29 CFR 1926.50).
• Prevention includes providing Safety Data Sheets (SDSs), ensuring proper hazardous materials training, using appropriate PPE, observing U.S. Department of Transportation (DOT) HAZMAT rules and implementing spill response plans.

Respiratory Hazards

Respiratory hazards arise from exposure to harmful dust, fumes, gasses or vapors, which can lead to serious health issues for construction workers who breathe in these materials.

• OSHA Standards mandate monitoring of airborne contaminants (29 CFR 1910.1000) and require the use of appropriate respiratory protection (29 CFR 1910.134).
• Prevention involves conducting air quality assessments, providing proper respirators, ensuring workers are trained in their use and implementing ventilation controls to minimize exposure.

Ergonomic Hazards

Ergonomic hazards occur when workers face repetitive motions, awkward postures or excessive lifting, leading to musculoskeletal disorders and injuries.

• OSHA Standards recommend assessing ergonomic risks in the workplace (29 CFR 1910.900) and implementing controls to reduce strain on workers.
• Prevention includes providing ergonomic training, using adjustable workstations, promoting proper lifting techniques and encouraging regular breaks to minimize fatigue.

Noise-Induced Hearing Loss

Noise-induced hearing loss occurs when workers are exposed to excessive noise levels on construction sites, leading to permanent hearing damage.

• OSHA Standards set permissible noise exposure limits (29 CFR 1910.95) and require hearing conservation programs for workers exposed to high noise levels.
• Prevention includes conducting regular noise assessments, providing hearing protection such as earplugs or earmuffs, training workers on the risks of noise exposure and implementing engineering controls to reduce noise levels.
