What is a Confined Space?
An enclosed or partially enclosed space under atmospheric pressure, not intended and not initially designed as working spot, and anytime
- is exposed to atmosphere containing potentially excessive contamination levels,
- experiences lack or excessive content of oxygen,
- causes absorption, or
- has limited means of entry and escape.
Examples of Confined Spaces
- Storage tanks, road tankers, boilers, bins, pipelines and other tank-type compartments
- Cavities, pits
- Mine shafts and tunnels
- Any ship spaces accessed through a hatch or an access point, cargo tanks (except for dry cargo holds)
Entries into the confined spaces conjugate to the uncharted danger of the enclosed atmosphere. For safe work and proactively identifying the danger before each entry, it is necessary to conduct an atmosphere analysis, as well as continuously monitoring the inside atmosphere.
For confined space entries without support points, MSA offers a unique system for personnel and cargo lowering into / rising from a confined space. The universal tripod provides a class B anchor point. Lifting is controlled by the MSA Workman Winch. Self-retractable lanyards serve as fall-arrest devices. The MSA Workman Rescuer provides fast, easy and intuitive fall protection with integral bidirectional retrieval capability.

In confined space areas with a constantly high potential for hazardous emissions, MSA offers combination supplied airline respirators operated by an airline trolley system to provide proper safety at work. If there is a risk for unexpected hazardous events, an escape device or an oxygen self-rescuer are the right choice to help workers escape from the confined space in case of oxygen deficient or toxic atmosphere.
Head, Eye and Hearing Protection
Regardless of what kind of work is carried out inside a confined space, it is necessary to use preventive personal protective equipment such as helmets and goggles. Working in the field of safety for more than 100 years, MSA offers a wide range of PPE for preventive protection.
