Respiratory Protection in Confined Space

Confined spaces often present unseen challenges. Confined spaces are areas that meet all of the following criteria:
- Large enough for workers to enter and perform certain jobs
- Limited or restricted means for entry or exit
- Not designed for continuous occupancy

Confined spaced. Unique challenges.

No two confined spaces are exactly alike. Type, size and hazards vary greatly, along with different standards, regulations and company policies that can apply to each working environment.

Common types of confined spaces

Safely handling entries and exits starts with identifying your work spaces:
- Storage tanks
- Culverts
- Tunnels
- Elevator shafts
- Ductwork
- Trench box
- Utility vaults
Where they are found

Working safely in confined spaces is universal, but different industries present their own challenges:
- Pharmaceutical manufacturing
- Chemical manufacturing
- Food and beverage manufacturing
- Oil and gas
- Waste water treatment

Developing a Confined Space Plan

Be ready before getting to work, so your team can safely handle all entries and exits.

Respiratory products for confined spaces

Confined spaces present some of the most challenging environments. When your in a toxic atmosphere exposed to respiratory hazards like combustible dusts, hazardous chemicals, or experience oxygen deficiency, you need respiratory protection that will support you.

Supplied air systems

Clean, breathable air can be delivered to hoods, helmets, full facepieces, half facepieces and loose-fitting facepieces. 3M supplied air respirators require a source of clean Grade D breathing air, such as plant air systems or bottled air.
Self-contained breathing apperatus

When hazards are so concentrated or so toxic they can't be brought to acceptable levels with other types of respiratory protection or if you've been unable to definitely record the level of hazard in the workplace, you may need a self-contained breathing apperatus.
Respirators

If you know the hazard in the workplace and the protection factor you need to meet, a negative-pressure respirator may be an option.
