Questions & Answers

Under 1919.22, which types of winches and cranes must be provided with means to stop and hold the proof load?

All types of winches and cranes aboard vessels must have a device or system that can stop and hold the proof load in any position. This is a clear requirement under 1919.22, which applies to certification of vessels' cargo gear.

Under 1919.22, must the stopping and holding means for winches and cranes be tested, and what does "efficiency demonstrated" mean?

Yes — the stopping and holding means must be tested so that their efficiency is demonstrated. 1919.22 requires the efficiency of the means to stop and hold the proof load to be demonstrated, which means the employer must run appropriate tests (proof-load or functional tests) that show the brake or holding device can reliably stop and hold the load under real conditions.

Under 1919.22, what must happen to electric winches, electrohydraulic winches with electromagnetic or hydraulic brakes, and electric cranes if electric power fails?

If electric power fails, the equipment must stop motion and set the brakes automatically without any action by the operator. 1919.22 explicitly requires electric winches, electrohydraulic winches fitted with electromagnetic or hydraulic brakes at the winch, and electric cranes to be equipped so a power failure stops motion and sets the brakes without operator intervention.

Under 1919.22, from where must current be taken when testing electric winches and cranes?

Current for operating electric winches and cranes during tests must be taken from the vessel's circuits. 1919.22 requires tests to use the vessel's electrical circuits so the equipment is tested under normal shipboard power conditions.

Under 1919.22, can shore power be used to operate electric winches and cranes during tests, and if so under what condition?

Yes — shore current may be used for tests, but only if it passes through the vessel's main switchboard. 1919.22 allows shore power for testing provided the ship's main distribution is used so the equipment sees the same electrical protection and routing as when on its own power.

Under 1919.22, are electromagnetic or hydraulic brakes located at the winch acceptable for meeting braking requirements?

Yes — electromagnetic or hydraulic brakes fitted at the winch are acceptable when used on electric or electrohydraulic winches. 1919.22 specifically includes electrohydraulic winches fitted with electromagnetic or hydraulic brakes at the winch in the equipment that must automatically stop and set the brakes on a power failure.

Under 1919.22, does the operator have to act to set the brakes if electrical power fails?

No — the brakes must set without any action by the operator when electrical power fails. 1919.22 requires automatic stopping and braking on loss of electric power so the operator does not have to take action to prevent load movement.

Under 1919.22, who should demonstrate the efficiency of braking and holding means for winches and cranes?

The employer is responsible for ensuring the efficiency is demonstrated, typically by a qualified or competent person designated by the employer. 1919.22 requires that efficiency be demonstrated, and OSHA guidance notes that employers assign or approve competent persons to identify hazards and take corrective actions (see the April 26, 1977 letter on competent-person procedures at https://www.osha.gov/laws-regs/standardinterpretations/1977-04-26).

Under 1919.22, does the automatic-stop-on-power-failure requirement change if the winch or crane is powered from shore current during normal operations?

No — the automatic-stop-and-set-brakes requirement still applies regardless of whether the source is shore power or the ship's generators, because shore current used for tests must pass through the main switchboard and equipment behavior on power loss must meet 1919.22.

Under 1919.22, do non-electric winches and cranes have to stop and hold the proof load if power (e.g., hydraulic or pneumatic) is lost?

Yes — all types of winches and cranes must have means to stop and hold the proof load in any position, but the specific automatic-stop-on-power-failure provision applies only to electric and specified electrohydraulic systems. 1919.22 requires stopping/holding means for all types, while the automatic setting of brakes on power loss is specifically required for electric and certain electrohydraulic equipment.

Under 1919.22, may an employer use a test power source that bypasses the vessel's electrical protection and main switchboard when performing brake-efficiency tests?

No — tests must use the vessel's circuits or shore current that passes through the main switchboard so the equipment is tested under the ship's normal electrical routing and protection. 1919.22 requires taking current from the vessel's circuits for testing.

Under 1919.22, is there an OSHA requirement to keep written records of the brake-efficiency demonstrations?

The text of 1919.22 requires that efficiency be demonstrated but does not prescribe a specific written-records format; however, employers have an overall duty to provide a safe workplace and documenting tests is a practical way to show compliance. OSHA has advised that employer responsibilities and the applicability of standards depend on workplace circumstances (see https://www.osha.gov/laws-regs/standardinterpretations/1991-02-19), so keeping written test records is a prudent compliance practice.

Under 1919.22, if a brake fails during a proof-load test, what immediate steps should the employer take?

The employer must stop testing and take corrective action to make the equipment safe before resuming tests or operations. 1919.22 requires that the means to stop and hold be effective; OSHA guidance on employer responsibility for safe workplaces (https://www.osha.gov/laws-regs/standardinterpretations/1991-02-19) supports stopping operations and correcting hazards immediately when protective systems fail.

Under 1919.22 and Part 1919 generally, do these braking and power-source rules apply only when gear is on the vessel, or do they also apply to shore-based gear used for vessel cargo operations?

Part 1919's rules are focused on vessel cargo gear and apply to gear installed on vessels; application to shore-based gear depends on the workplace and operation. 1919.22 governs vessel cargo gear, and OSHA has explained that which standards apply depends on the specific workplace circumstances (see https://www.osha.gov/laws-regs/standardinterpretations/1991-02-19). If shore-based equipment is part of a vessel's cargo operations or otherwise covered by maritime standards, the employer should confirm the applicable standard and ensure compliance.
