Don’t get caught in a tight space!

OSHA (Occupational Safety and Health Administration) has released a factsheet (29 CFR 1926 Subpart AA) on all the rules and regulations of residential workers in confined spaces. OSHA works to assure the safety and health of all of America’s working people.

This blog highlights what we think are the key points.

Well, how is a confined space defined?

OSHA defines these as

  • has limited entry and exits
  • larger enough for workers to enter
  • not intended for regular occupancy

Confined space sites could be drains, manholes, water mains, sewer systems, crawl spaces, attics, heating, ventilation, and air-conditioning systems.

There are two different variants on confined spaces. Those that contain hazardous conditions and those that do not contain a physical hazard to the individual.

A confined space that contains hazardous conditions could be considered a permit-required space under the new regulations (PRCS). These spaces might be dangerous to the life of the worker if the space hasn’t been investigated, tested and controlled.

Spaces that tend not to be permit-required confined spaces generally do not contain life threatening hazards. Attics, basements and crawl spaces have a smaller risks but still fall into new regulations.

I’m an employer. What do I need to do?

  • Evaluate the space! If hazardous conditions are present, a permit specifying safety measures and names of those permitted in the space must be written before any work can take place.
  • Inform employees! Let your employees know all the facts. Does a workplace contain a confined space? Is this a permit-required space? All workers should be informed of these hazards – these only needs to be a signpost for entry and exit points if required.
  • Protection! Attempt to remove or isolate any hazards that may be present in the space.
  • Have the right equipment! Check out our range of Portables that would help protect your employees from hazardous gases.
  • Train your staff! Workers should be aware of the dangers and understand any hazards in places permits are required.

Still not clear? Don’t worry, the factsheet offers insight and obligations for all kinds of employers.

Under the new standards, the obligation of the employer will depend on what type of employer they are. The controlling contractor is the main point of contact for any information about PRCS on site.

  • Host employer: The employer who owns or manages the property where the construction work is taking place.
  • Controlling contractor: The employer who has overall responsibility for construction at the worksite.
  • Entry employer or Sub Contractor: Any employer who decides that an employee it directs will enter a permit-required confined space.

How are the new regulations different to the previously applied rules?

The guidelines require employers to figure out what confined spaces their employees are working in, what hazards there are and how these can be made safer, develop rescue plans and ensuring staff training.

Successful aspirations

Good confined space entry procedure requires the use of a pumped portable detector to check the space is safety to enter. But some detectors don’t have pumps built in, in which case, an aspirator should be used. An aspirator is a manual system for drawing the air through a tube to the sensor, and it can work well. However, it is something that requires practice to give confidence that you are doing it right.

Hydrogen Sulphide Hazards

Next in our series of short videos is our hydrogen sulphide detection factoid.

Where is H2S found?

Hydrogen sulphide is a significant danger to workers in many industries. It is a by-product of industrial processes, such as petroleum refining, mining, paper mills, and iron smelting. It is also a common product of the biodegradation of organic matter; pockets of H2S can collect in rotting vegetation, or sewage itself, and be released when disturbed.

Carbon Dioxide – Friend and Foe?

Carbon dioxide (CO2) gas is commonly used in the manufacture of popular beverages. The leak at the Greene King brewery in Bury St Edmunds (UK) last week, is a reminder of the importance of effective gas detection. It resulted in twenty workers having to be rescued by emergency services and local residents being evacuated. So what is carbon dioxide, why is it dangerous and why do we have to monitor it carefully?

Confined spaces still deadly places

 Despite the significant amount that has been published about the dangers of confined space entry, recent evidence in the news suggests that people still do not fully understand the risks or take appropriate precautions. In the news this week, Dorset farm owner has been fined for serious safety failings after one of his workers died following exposure to toxic gases escaping from a tank during tank maintenance.

Getting yourself out of a hole

A common question we encounter at Crowcon is when to use a pump or aspirator with a portable gas detection device. I’d like to share some thoughts about the use of personal detectors with pumps or aspirators as part of an effective confined space pre-entry check.
