Many sites follow a helmet color code. Red helmets are commonly used for visitors, making them easy to identify and supervise. Workers and supervisors usually wear other colors.

Continuous loud noise from machinery and tools can cause hearing loss. Ear protection reduces sound exposure, preserving workers’ hearing health.

Carbon monoxide is a toxic gas produced by engines and combustion. Since it has no smell or color, workers may not notice exposure until it is too late. Proper ventilation and detectors are essential.

Guardrails are installed on scaffolding platforms to create a protective barrier, ensuring that workers do not accidentally step off or lose balance and fall. They are part of fall protection systems, which are critical since falls are among the leading causes of fatalities in construction.

Paint fumes can contain harmful chemicals like VOCs that damage lungs. Respirators prevent inhalation, protecting long-term respiratory health.

Construction near rivers, ports, or bridges involves the risk of drowning. Life jackets and safety boats provide immediate protection, and rescue equipment ensures quick response in emergencies.

Seat belts prevent operators from being thrown out of their seats during sudden stops, rollovers, or collisions. Remaining inside the cab significantly reduces injury risks.

Metal fires burn at very high temperatures and react violently with water or foam. Dry powder extinguishers smother the flames and absorb heat, making them ideal for Class D fires.

Before demolition, all utilities must be disconnected to avoid fire, explosions, or electrocution. A controlled and safe procedure prevents accidents during demolition.

A safety harness, when connected to a secure anchor point, ensures that a worker does not fall to the ground if they slip or lose balance. Other PPE items like reflective jackets and ear plugs are useful, but for fall protection, a safety harness is the most critical.
