In a confined space what three hazards can occur?

In a confined space, three main hazards can occur:

1. Oxygen Deficiency: Confined spaces often have limited ventilation, which can lead to a decrease in oxygen levels. When oxygen levels drop below 19.5%, it can cause dizziness, nausea, impaired judgment, and eventually unconsciousness and death.

2. Toxic Atmospheres: Confined spaces may contain hazardous gases or vapors, such as carbon monoxide, hydrogen sulfide, or volatile organic compounds (VOCs). These gases can be released from stored chemicals, leaking pipes, or natural processes like decomposition. Inhalation of these gases can cause severe health effects, including poisoning, suffocation, and even death.

3. Fire and Explosion Hazards: Confined spaces can accumulate flammable gases, vapors, or dust, creating a high risk of fire and explosion. Sources of ignition can include electrical sparks, open flames, or hot surfaces. Fires and explosions in confined spaces can cause severe burns, structural damage, and fatalities.
