Do I need a tripod/winch if my confined space has a ladder?

Upon initial inspection and evaluation of the confined space, if it is determined that a person could be injured in such a way that he/she would not be able to self-rescue (e.g., climb a ladder), then a retrieval system is necessary. If entering a confined space where the potential for a fall could occur (i.e., a person could slip or lose control climbing a ladder), then fall protection must be included in the confined space entry system. A self-retracting lifeline with a winch retrieval system provides rescue retrieval for a worker entering a confined space should he/she become incapacitated. It is the responsibility of the employer to evaluate EACH space separately, and develop entry and rescue procedures for EACH individual space, according to 29 CFR 1910.146(d)(3) and 29 CFR 1910.146(d)(4). Generally speaking, according to the Preamble to the Confined Space Standard, at a depth of 5 ft. or greater, some form of mechanical means is needed to extract the worker from a vertical confined space.

Can I use any harness for confined space entry using a tripod and winch system?

Any harness with a front and/or back D-ring attachment can be used for confined space entry applications. If using a hoist for lowering a worker into a confined space, you may attach the hoist to the front D-ring if that is a feature on the harness. This allows the worker to be lowered in a comfortable sitting position. Connecting to the rear (dorsal) D-ring on the harness is normally suggested because if a rescue is ever required, the lift position has less chance of interfering when being hoisted-from/exiting the confined space opening. For more information regarding Confined Spaces, check: www.osha.gov for 29 CFR 1910.146. Or Check Quick Tips #115: Confined Spaces, 29 CFR 1910.146

What standards are available for cable management?

British Standard recently adopted the Requirements for Electrical Installations [BS7671:2018] for the industry electrical design industry. This standard can have an effect on how you utilize the CableSafe Safety Hooks. This standard is developed after the deaths of two firefighters at Harrow Court,

Hertfordshire, UK in 2005. The two firefighters got entangled as a result of the collapse of an electrical installation during a fire. The implemented standard states that it requires cables to be adequately supported against their premature collapse in the event of a fire.

OSHA: What is the difference between a cable and a cord?

Subpart S does not define “cable” or “cord.” However, the National Fire Protection Association (NFPA) which publishes a consensus standard, on which Subpart S is based, but which OSHA does not enforce, offers guidance on the meaning of these terms. Specifically, NFPA 79-2012(1) provides the following definitions: Flexible Cable – A cable or special cable manufactured with flexing or constant flexing properties. Cable – A combination of conductors insulated from one another with a common covering that is not a cord. Cord – Two or more flexible insulated conductors enclosed in a flexible covering that provides mechanical protection.

Why use S-hooks or Safety Hooks?

The patented CableSafe® Safety Hooks are applied in maintenance, turnaround, construction and industrial works as product to suspend hoses, cables and work gear off the work floor. CableSafe® Safety Hooks are used by most multinationals in e.g. refineries, chemical plants, shipbuilding, electrical and nuclear installations.

What are the strength requirements for fall-arrest system anchors?

Fall-arrest system anchors must be capable of supporting a static load of 5,000 lbs. for each worker connected to an anchorage point, unless engineering certification exists. Anchorage points that have engineering certification must still maintain a safety factor of at least 2:1 when the system is designed, installed and used under the supervision of a qualified person. Fall-arrest systems must limit a fall to 6 ft., according to ANSI A10.14-1991, OSHA 1926.502.

What are the different types of fall protection equipment?

There are two major types of fall arrest: general (nets) and personal (lifelines). The fall arrest systems only comes into service when or if a fall occurs. According to OSHA standards, only retractable lifelines, or full-body harnesses with shock-absorbing lanyards are accepted as personal fall arrest systems.
