Confined Space Safety & Online Training for Workers

Introduction

Confined spaces in construction can be hazardous due to restricted entry and exit, limited airflow, and potential dangers inside. Workers may be exposed to hazardous gases, low oxygen levels, or other safety risks. Common confined spaces include tanks, tunnels, sewers, crawl spaces, manholes, and trenches. Understanding these hazards and following proper safety measures is important for protecting workers.

Fire and Explosions: Confined spaces may contain flammable substances in the form of gases, vapors, or dust. Flammable gases like methane or acetylene can be especially dangerous, even in areas with low oxygen levels. A single spark from a tool or equipment can ignite these substances, leading to a fire or explosion. Limited airflow in confined spaces can make the situation worse, as fires may spread quickly, be difficult to control, and cause injuries or fatalities.

Other Dangers

Workers in confined spaces may also face additional hazards, including:

Falling Objects: Tools, loose materials, or debris can fall from above and hit workers, causing serious injuries.

Extreme Heat: Limited airflow can cause heat to build up, making the space dangerously hot and leading to heat exhaustion or heatstroke.

Loud Noises: Noise from machinery or equipment can damage hearing over time and make it harder to hear warnings.

Limited Movement: Workers may have to bend, twist, or remain in awkward positions for extended periods, increasing the risk of muscle strain or injury. It can also slow down escape in emergencies.

How to Stay Safe in Confined Spaces

Permit-Required Spaces: Some confined spaces, like tanks, silos, or sewers, are extremely dangerous due to risks such as toxic gases, low oxygen, or engulfment. A special permit is required before entry to confirm that proper safety measures are in place. Only trained workers with the right safety equipment should go inside.

Good Ventilation: Proper ventilation, such as exhaust fans or air blowers, helps remove harmful gases and maintain safe oxygen levels. Good airflow makes it easier to breathe and lowers the risk of toxic exposure.

Air Testing: The air inside must be tested using gas detectors before entry to check oxygen levels and detect harmful gases. Regular testing during the job helps monitor conditions and prevent hazards.

Protective Gear: Workers should wear helmets, gloves, respirators, and harnesses to protect against falling objects, toxic gases, or other hazards.

Emergency Plans: A rescue plan must be in place before work begins. If a worker gets trapped or needs help, a trained rescue team with proper equipment, such as retrieval systems and supplied-air respirators, should be ready to respond immediately.

Ongoing Safety Checks: Workers should always monitor conditions and stop working if new dangers arise. If any sign of danger appears, they should leave the confined space right away.
