An entry permit must be completed and signed by the responsible supervisor before a worker enters a confined space:
With a high-hazard atmosphere,
- That requires lockout or isolation procedures to be followed, or
- In which there is a hazard of entrapment or engulfment.
- Once issued, the information on an entry permit may only be altered by:
- The responsible supervisor who signed the permit to update it,
- The standby worker to update the list of workers inside the confined space, or
- The tester to record test results.
- Before a worker enters a confined space, adjacent piping which contains or has contained a harmful substance must be controlled by:
- Disconnecting, blanking or blinding, or equivalent engineered system, or
- If the adjacent piping contains a harmful substance that is not a gas or a vapour, nor a liquid of sufficient volatility to produce a hazardous concentration of an air contaminant in the discharge of the piping, a double block and bleed system.
- Corsafety.ca must take all steps reasonably practicable to prevent any person, other than a worker who is required or permitted to do so, from entering a confined space.
If there is a possibility of unauthorized entry into a confined space, Corsafety.ca shall ensure that each entrance to the confined space is adequately secured against unauthorized entry or has been provided with adequate barricades, adequate warning signs regarding unauthorized entry, or both.
Before each shift, a competent person shall verify that the entry permit complies with the relevant plan.
Whenever a worker is to enter a confined space, Corsafety.ca shall ensure that an attendant is designated, assigned and stationed outside and near the entrance to the confined space.
