When a pressurized air hose becomes accidentally uncoupled or a hose or fitting failure occurs, the rapid expansion of air causes the hose to whip violently creating a potentially lethal situation. Use whipchecks to help prevent injuries or accidents resulting from hose or coupling failure. A whipcheck extends across the hose fittings to give standby safety for hose. Simply pull back the spring and slip the loops on the whipcheck over each hose before connection to provide
Hose To Tool whip checks
These whip checks Prevent hoses from whipping if couplings are accidentally disconnected. whip checks are made from steel cable ( stainless option) and meet OSHA and MSHA (Mine Safety and Health Administration) safety standards. Maximum working pressure is 200 psi.
Hose-to-hose whip checks have spring-loaded loop ends that sucure over the hose ends for a firm grip. Hose to tool whip checks have a spring load loop on one end and a choker on the other.
Whipchek air hose restraints are slipped over the hose on each side of the fitting and prevent hose whip in the event of fitting separation or failure. Spring loaded loops on each end are easily opened to pass over the fitting and then provide a firm grip on the hose.
The spring loaded loop is placed over the hose, and the choker end is wrapped around the tool handle or pipe outlet and cinched tight in a choker configuration.
MSHA 30 CFR § 56.13021
High-pressure hose connections
Except where automatic shutoff valves are used, safety chains or other suitable locking devices shall be used at connections to machines of high-pressure hose lines of 3/4-inch inside diameter or larger, and between high-pressure hose lines of 3/4-inch inside diameter or larger, where a connection failure would create a hazard.
OSHA 29 CFR § 1926.302(b)(1)
Pneumatic power tools shall be secured to the hose or whip by some positive means to prevent the tool from becoming accidentally disconnected.
Personal Protective Equipment
• Fit-for-purpose PPE, as prescribed in the risk assessment and SWMS, shall be available and: • Meet the appropriate government Standard where applicable. • Be appropriate for the person and the task. • Be used as per the original equipment manufacturer directions. • Be inspected regularly and before each use for wear, damage and ‘use-by’ dates. Hoses and components The following safety precautions are to be taken in regards to air hoses: • Ensure all hoses and components are appropriately rated to handle the maximum operating pressure of the air compressor. • Ensure that hoses are protected from mobile plant and vehicle traffic with suitable positioning or cover ramps. • Always release the pressure in air hoses and tools prior to uncoupling. • Never kink or squash a hose to permit it, or a tool attached to it, to be uncoupled. • Always close the valve to which the hose is connected when not in use. • All airlines are to be stored off the ground so that no dirt entry is possible at hose ends. • Always secure couplings use, whip checks, and check to confirm attached and secure • Do not use compressed air hoses for other products such as oils or fuels. • Always ensure that the output hose is secured to an implement prior to turning on air supply. • Do not fit a tail-tail component to extend air hoses. Always use appropriate couplings. • Bolted clamps, that are appropriately secured, shall always be used to secure hoses to hose fittings. • Inspection and maintenance • Employers are required to establish an inspection and maintenance regime for all compressed air equipment. This regime shall be based on: • The results of the risk assessment for the equipment. • The relevant government Standards for each component. • The age and condition of the equipment. • All inspection and maintenance activities are required to be documented (e.g. completed checklists, service reports) and any defects promptly taken out of service and repaired or replaced. • No maintenance work is to be undertaken on air compressors or compressed air tools unless the equipment has been completely de-energised and locked out by the maintenance personnel.
