What should you do after checking for oxygen levels in a confined space?

After checking for oxygen levels in a confined space, the next logical step is to check for combustible gases or vapors. This is crucial because even if oxygen levels are acceptable, the space could still pose a significant danger due to the presence of flammable materials.

Combustible gases can ignite and cause explosions or fires, leading to life-threatening situations for anyone working in that environment. Therefore, verifying the absence of dangerous levels of combustible gases or vapors ensures that the atmosphere is safe for work.

While exiting the space, starting work immediately, or notifying a supervisor may also be necessary actions in certain contexts, the immediate step following the verification of oxygen levels should primarily focus on identifying other hazardous conditions that could impact safety. This step is integral to maintaining a safe working environment and ensuring that all necessary precautions are taken before proceeding with any work.
