Study Notes

Physical Hazards in Confined Spaces

Bodily injury from slips and falls is linked to surface residues, emphasizing the need for safe surfaces in confined areas.

Respiratory Protection

When sufficient ventilation is unavailable, employees must use airline respirators for protection in confined spaces.

Oxygen Levels

A safe atmosphere must maintain at least 19.5% oxygen; precautions are required to prevent exposure to lower levels.

Employee Training Requirements

All employees must understand the nature of hazards, necessary precautions, and the usage of protective and emergency equipment before entering confined spaces.

Secondary Irritant Atmospheres

Defined as those that can cause toxic effects on the body, highlighting the importance of monitoring air quality.

Types of Confined Spaces

Examples include sewers and storage tanks, which are identified as confined spaces requiring special precautions.

Function of Tanks

Tanks are used for various purposes, particularly for storing water and chemicals, necessitating safety measures during entry.

Limitations of Entry and Exit

Entry and exit time can pose significant physical limitations, impacting potential hazards within the confined space.

Atmosphere Testing Protocols

Regular testing of atmospheric conditions is essential; it should be conducted as often as necessary to ensure safety.

Classification of Hazards

Hazards in confined spaces can be categorized by material used, activities performed, and the external environment, ensuring comprehensive safety evaluations.
