Confined spaces are hard.

No two job sites are the same but many have one thing in common - Confined Space.

So how do you know if your worksite has one?

Confined spaces...
  • are large enough so that a human can enter and perform assigned task
  • have limited or restricted access
  • not assigned for continuous use by personnel

Some confined spaces require special permits to access due to safety concerns such as engulfment, entrapment or asphyxiation.

Confined spaces greater than 5 ft. require:
  • all occupants wear a fall arrest harness
  • and a mechanical rescue system be ready for use in case of need.

This rule applies to all non-classified confined spaces.

ABC's of Confined Spaces

A simple way to think about confined space solutions...

Anchors (a)

Anchors Davit systems, tripods and portable fall arrest posts are solutions where the worker’s fall protection connector will be attached and is the main source of retrieval for the attendee.

Confined space solutions need to be anchored to a structure and are what the connector (c) attaches to. Anchors are:

  • Davit systems
  • Tripods
  • Portable fall arrest systems

Body Support (b)

Body Support Harnesses and work seats are two types of solutions that are designed to support the weight of the worker’s body.

Body support refers to what is supporting the users weight, usually in form of:

  • Full body harnesses
  • Work seats

Connectors (c)

Connectors Winches and retrieval SRL's are the most common type of connector for confined spaces.

Connectors are the "middle-man" between the anchor and the body support - most commonly:

  • Winches
  • Retrieval SRL's
