Aircraft Equipment And Material Hazards Flashcards
What gases are essential for aircraft systems?
Air, nitrogen, carbon dioxide, and oxygen.
How must essential gases be maintained?
In the correct quantities in their respective containers and replenished at each appropriate servicing opportunity.
How are gases supplied to aircraft systems?
Under pressure from large cylinders, normally mounted on a trolley.
What connects the cylinders on a gas charging trolley?
Pipelines to a charging regulator assembly.
What can result from incorrect charging of aircraft gas systems?
Serious accidents.
What are the common mistakes leading to accidents in gas charging?
Using incorrect charging equipment and failing to observe specified precautions.
What is the color of air cylinders?
Air cylinders are grey.
What is the color of nitrogen cylinders?
Nitrogen cylinders are grey with a black top.
What is the color of breathing oxygen cylinders?
Breathing oxygen cylinders are black with a white top.
How are the gas types marked on the cylinders?
All cylinders should have the gas type printed onto the cylinder body.
What is the purpose of marking the trolleys and cylinders?
To avoid any possible confusion.
What are the hazards associated with compressed gas misuse?
Injection of compressed gases and pressurized lubricants into the skin can result in serious injury or death. Pneumatically operated lubricating equipment can generate very high pressures at the lubricating gun.
What risk exists when introducing compressed air or oxygen into contaminated enclosed volumes?
A high risk of explosive combustion exists due to the ‘dieseling’ effect.
What can result from the misuse of compressed gas or pneumatic lubricating equipment?
Damage to equipment or aircraft may occur.
What must personnel understand before servicing gaseous oxygen systems?
The nature and properties of the gas, as well as the hazards and safety precautions.
What incident has occurred involving servicing personnel and oxygen?
Injuries have occurred due to spontaneous combustion of oil and grease coming into contact with high-pressure oxygen escaping from charging hoses.
What do the Provision and Use of Work Equipment Regulations (PUWER) require?
Employers must ensure that work equipment is serviceable and safe.
What checks should personnel undertake for work equipment?
Personnel should comply with work equipment information, instructions, and undertake daily visual checks prior to use.
What should personnel do if they find equipment unsafe or defective?
They must immediately inform the supervisor.
What accounts for about half of all work-related ill-health?
Work-related injuries resulting in musculoskeletal disorders.
What do the Manual Handling Operations Regulations require employers to do?
Employers must risk assess manual handling tasks and introduce management controls to reduce injury risk.
What responsibilities do personnel have regarding manual handling?
Personnel should comply with safe systems of work and report any deficiencies, as well as inform management of any conditions affecting their ability to handle loads safely.
What training should be provided for manual handling tasks?
Adequate information, instruction, and training should be given to undertake the task safely.
