ACTION ALREADY TAKEN TO REDUCE THE RISKS
Compliance with:
HSE Guidance L101 - Entry into Confined Spaces
Local Authority/client safety standards, e.g. on sewer entry.
Entry into Confined Spaces Regulations 1997
The Construction (Design and Management) Regulations 2015
Dangerous Substances and Explosive Atmospheres Regulations 2002
Planning:
Eliminate need for entry or use of hazardous materials by selection of alternative methods of work or materials. Assessment of ventilation available and possible local exhaust ventilation requirements, potential presence of hazardous gases/atmosphere, process by-products, need for improved hygiene/welfare facility. Prepare a method statement for the work.
Physical:
Documented entry system will apply, with a Permit to Work and method statement. Adequate ventilation will be present or arranged. Detection equipment will be present before entry to check on levels of oxygen and presence of toxic or explosive substances. The area will be tested before entry and continually during the presence of persons in the confined space. Breathing apparatus or airlines will be provided if local ventilation is not possible. Where no breathing apparatus is assessed as being required, emergency BA and rescue harnesses will be provided. Rescue equipment including lifting equipment, resuscitation facilities safety lines and harnesses will be provided. A communication system with those in confined space will be established. Air will not be sweetened with pure oxygen. Precautions for safe use of any plant or heavier-than-air gases in the confined space must be established before entry. Necessary P PE and hygiene facilities will be provided for those entering sewers.
Managerial/Supervisory:
The management role is to decide on nature of the confined space and to put a safe system into operation, including checking the above and preparing a method statement.. Flood potential and isolations must be checked.
Training:
Full training required for all entering and managing confined spaces. Rescue surface party to be trained, including first aid and operation of testing equipment. All operatives must be certified as trained and supervisory staff trained to the same standard. All persons entering a confined space should be physically fit.
