Date of Adoption: April 20, 2004.
Purpose: Chapter 296-829 WAC, Helicopters used as lifting machines; chapter 296-24 WAC, General safety and health standards; and chapter 296-155 WAC, Safety standards for construction workers.
The helicopter rules in chapter 296-24 WAC, General safety and health standard and chapter 296-155 WAC, Safety standards for construction workers, were rewritten and reorganized for clarity and ease of use for employers and employees. The two sections have become one rule and placed into new chapter 296-829 WAC, and repealed from chapters 296-24 and 296-155 WAC. This rule making is part of our clear rule-writing initiative to rewrite for clarity all of the safety and health rules.

HELICOPTERS USED AS LIFTING MACHINES
|Exemption:||This chapter does not apply to the use of helicopters:|
|• In the logging industry.|
|• For rescue operations when a winch or hoist is used.|
To make sure your helicopters meet design specifications and are equipped properly.
Follow Federal Aviation Administration (FAA) requirements
Install and test hooks on helicopters correctly
• Make sure helicopter cranes and their use meet the applicable requirements of the Federal Aviation Administration (FAA).
• Make sure electrically operated cargo hooks are:
– Designed and installed to prevent accidental operation.
– Equipped with an emergency mechanical control to release the load.
• Make sure a competent person tests all hooks before each day's operation to make sure both the electrical and mechanical releases work properly.
To keep helicopters in safe operating condition.
Keep landing and deposit areas safe
Follow safe refueling procedures
(1) Make sure precautions are taken to prevent loose objects from being caught in the downwash and flying around.
• Secure or remove all loose gear:
– Within one hundred feet of lift and deposit areas.
– In all other areas affected by rotor downwash.
(2) Make sure employees do not work under hovering craft, except where necessary to hook or unhook loads.
(3) Make sure safe access and exit, including an emergency escape route, is provided for employees who hook or unhook loads.
(4) Prohibit open fires in any area that could be affected by the rotor downwash.
(5) Make sure unauthorized people do not go within fifty feet of the helicopter when the rotor blades are turning.
(6) Make sure all employees:
• Stay in full view of the pilot, in a crouched position, when approaching or leaving a helicopter with rotating blades.
• Stay away from the area behind the cockpit or cabin unless the operator authorizes them to work there.
(7) Take precautions to eliminate reduced visibility.
(8) Make sure ground personnel take special care to stay clear of rotors when visibility is reduced by dust or other conditions.
• Make sure refueling areas are safe.
– Post "NO SMOKING" signs at all entrances to the refueling area.
– Provide at least one thirty-pound fire extinguisher, or a combination totaling thirty pounds, good for class A, B, and C fires, within one hundred feet on the upwind side of the refueling operation.
|Reference:||For additional requirements relating to portable fire extinguishers, see WAC 296-800-300 in the safety and health core rules.|
• Make sure workers involved in refueling are trained in both:
– The refueling operation;
– The use of fire extinguishing equipment they may need.
• Make sure the following precautions are taken before and during refueling:
– Keep unauthorized people at least fifty feet away from the refueling operation or equipment.
– Prohibit smoking and open flames within fifty feet of the refueling area or fueling equipment.
– Make sure helicopter engines are shut down before refueling, if using aviation gasoline or jet B type fuel.
– Pump fuel, either by hand or power.
– Use self-closing nozzles or deadman controls:
&sqbul; Do not allow these to be blocked open.
– Make sure nozzles are not dragged along the ground.
– Make sure the helicopter and the fueling equipment are grounded.
– Electrically bond the fueling nozzle to the helicopter:
&sqbul; Do not use conductive hose for this bonding.
– Make sure all grounding and bonding connections are:
&sqbul; Electrically and mechanically firm.
&sqbul; On clean unpainted metal parts.
• Stop fueling immediately if there is a spill:
– Do not continue operation until the person in charge has determined it is safe.
To make sure helicopters are operated safely.
Hold daily briefings
Make sure employees are dressed correctly
Make sure loads are attached correctly
Make sure the load is handled correctly
• Make sure the helicopter pilot and ground personnel hold a briefing before each day's operation to discuss cargo-handling plans.
• Make sure employees receiving the load:
– Do NOT wear loose-fitting clothes that could snag on the hoist line.
– Wear personal protective equipment (PPE), including complete eye protection and hard hats that are secured by chin straps.
|Reference:||For other requirements relating to PPE, see WAC 296-800-160 in the safety and health core rules.|
• Make sure loads are properly slung so tag lines cannot be drawn up into rotors.
• Make sure precautions are taken on all freely suspended loads to keep hand splices from spinning open or cable clamps from loosening, such as using pressed sleeves or swedged eyes.
• Make sure the weight of the load does not exceed the manufacturer's load ratings.
• Make sure hoist wires and other gear are not attached to or allowed to catch on any fixed structure.
|Exemption:||This requirement does not apply to pulling lines or conductors that "pay out" from a container or reel.|
• Make sure signal systems, whether radio or hand signals, are checked before hoisting the load:
– When using hand signals, use those shown in Figure 1.
• Make sure workers on the ground do either of the following before touching the suspended load:
– Use a ground device to safely discharge any static charge;
– Put on and wear rubber gloves.
• Make sure there are enough employees for safe loading and unloading operations.
• Make sure constant communications are maintained between the pilot and signal person:
– The signal person must be distinctly recognizable from other ground personnel.
