Why Fall Protection is Necessary in Confined Spaces

A confined space is defined as an area that's not easily accessible, not intended for long-term occupancy, characterized by limited entry and exit points, and poses potential hazards. OSHA has a specific definition of "permit-required confined space," which is any area that contains or has:

• The potential to contain a hazardous atmosphere
• Materials that could engulf anyone who enters
• Walls that converge inward
• Floors that slope downward to a smaller space that could trap or asphyxiate an entrant
• Any other recognized safety or health hazards, including unguarded machinery, exposed live wires, or heat stress

Before starting work in confined spaces, employers must identify and evaluate potential risks to determine the necessary precautions. Some potential risks include:

• Limited Access and Egress: Confined spaces often have restricted entry and exit points, making it challenging to escape quickly in the event of a fall.
• Height-Related Hazards: Some confined spaces may have vertical openings, such as pits, wells, or tanks, where workers may be exposed to fall hazards.
• Unstable Surfaces: Confined spaces may have uneven or unstable surfaces, leading to an increased risk of slips, trips, and falls.
• Potential for Atmospheric Hazards: Confined spaces may contain atmospheric hazards such as low oxygen levels, toxic gases, or flammable substances.

Types of Fall Protection Requirements for Confined Space Work

As an employer, it is of utmost importance that you follow a well-defined system of procedures and precautions for your employees before any worker enters a confined space requiring a permit. Remember, any deviation from the permit standards necessitates an immediate evacuation of the confined space. It is crucial that no employee, including rescue workers, enters a confined space without proper training and equipment. This includes Personal Protective Equipment (PPE) since more than 60 percent of all confined space fatalities occur because attendants or unauthorized personnel rush into hazardous environments without proper protection.

Non-Entry Rescue Procedures

These procedures should be promptly executed in case of an emergency without putting additional personnel at risk. Non-entry rescue procedures may involve the use of retrieval systems, tripod hoists, or other equipment designed for safe extraction without the need to enter the confined space.

Mechanical Devices and Full-Body Harnesses

Mechanical devices such as winches or hoists can be utilized as part of fall protection systems to retrieve workers from confined spaces. OSHA recommends using personal fall arrest systems (PFAS), such as a tripod/davit system, to prevent falls and protect workers from injuries. Full-body harnesses with an attached lifeline should be worn by workers entering confined spaces to ensure maximum safety.

Continuous Occupancy Requirements

OSHA regulations necessitate that confined spaces are continuously monitored, with specific requirements to ensure that atmospheric conditions are monitored and proper ventilation is maintained.

Emergency Retrieval Equipment and Systems

As mentioned, emergency retrieval equipment such as tripods, davit arms, or mechanical hoists may be required for use in confined spaces. This equipment is crucial for quickly and safely extracting workers in an emergency.

Expertise of Safety Professionals and Health Professionals

To comply fully with applicable federal and provincial regulations, such as OSHA's standard on confined spaces, 29 CFR 1910.146, it's essential to seek advice from safety and health professionals, including industrial hygienists. By relying on their expertise, employers can ensure a safer work environment for employees.

Potential Hazards in Confined Spaces Requiring Fall Protection

Confined space workers face a wide range of potentially dangerous situations, but one of the most overlooked hazards is the risk of slips, trips, and falls. Such hazards can occur at any point, from entry to exit, even while the worker performs their duties within the confined space.

Accidental Falls from Height or into a Hazardous Atmosphere

Personal fall arrest systems (PFAS) with full-body harnesses are commonly used to prevent falls. Guardrails, safety nets, and controlled access zones may also be employed. For atmospheric hazards, proper ventilation and continuous atmospheric monitoring are crucial.

Human Occupation, Mechanical Advantage, or Average Person Weight Requirements

Employers should follow the manufacturer's guidelines for weight limits on equipment. This may include using equipment like self-retracting lifelines (SRLs) or lanyards designed for specific weight capacities.

Possible Spreader Bar Applications for Heavy Loads and Feet Deep Environments

Spreader bars, when used, should meet OSHA standards for design, inspection, and usage. Employers may also use additional equipment, such as hoists or winches, to safely manage heavy loads.

Industrial Hygienists and Other Health Representatives Needed to Monitor Atmosphere Changes

While not directly related to fall protection, continuous atmospheric monitoring equipment is essential. Employers may also consider implementing emergency retrieval equipment to quickly extract workers in the event of an atmospheric hazard.

It's crucial to stay up to date with the specific OSHA regulations and standards for confined spaces to ensure compliance with the latest requirements and guidelines. Employers should also provide comprehensive training to workers on the proper use of fall protection equipment and procedures specific to the confined spaces they may be working in.
