From potentially toxic atmospheres, to physically hazardous conditions such as extreme temperatures, unstable materials, or the potential for falls, confined spaces often present unseen challenges. Confined spaces are areas that meet all of the following criteria:
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.
Safely handling entries and exits starts with identifying your work spaces:

Supplied air respirators can be either constant flow or pressure demand. 3M Scott Supplied Air systems are pressure demand and include 3M™ Scott™ Ska-Pak Respirators with an escape cylinder and the 3M™ Scott™ E-Z Airline Respirator without an escape cylinder. Respirators that include a cylinder can be used in environments that are immediately dangerous to life or health (IDLH). SAR users can work up to 300 feet away from the air source and for extended periods of time.
These systems can be used to work in, or escape from, hazards including those that are immediately dangerous to life or health (IDLH). An SCBA offers the greatest user mobility and can be used for work duration up to 75 minutes.
