Potential Hazards in Aircraft

Maintenance Engineering• Physical hazards may include: • Very bright lights (e.g. from welding)• very loud sounds (sudden or continuous)• confined or enclosed areas• working at significant heights• noxious substances (liquids, fumes, etc.)• excessive temperature (i.e. too cold or too hot)• moving equipment, moving vehicles and vibration

04/28/2023Chapter 9 3

A maintenance organization has a duty under health and safety legislation to• identify hazards in the workplace• remove them where possible• mitigate the risks to employeesIf hazards cannot be removed from the workplace, employees should be made aware that they exist and how to avoid them. This can be effected through training and warning signs. To be effective, warnings signs must

• AMEs should be made aware of hazards through Training and Warning Signs

• Warning Signs must: clearly identify the hazard(s) describe the danger (i.e. electric shock, radiation,

etc) inform employees what to do or not to do

04/28/2023Chapter 9 5

• DANGER denotes that the hazard is immediate and could cause irreversible damage or injury.

DANGER signs use red, black and white.• CAUTION indicates a hazard of lesser magnitude.

CAUTION signs are generally yellow and black.

Engineer’s Individual Responsibiliti

es• Every aircraft maintenance engineer should be

aware that he can influence the safety of those with whom he works

• Engineers should ensure that they keep the working environment safe. Clutter, rubbish, etc. is not only a nuisance to others, but can constitute a danger (e.g. a fire hazard, etc.).

• In addition, engineers should be careful when working on the line not to leave objects when a job has been completed.

Foreign Object Damage(FOD) is a risk to aircraft operating at an airfield

Dealing with Emergencies

• All personnel should know as far as reasonably practical how to deal with emergency situations.

Emergencies may include• An injury to oneself or to a colleague• A situation that is inherently dangerous, which

has the potential to cause injury (such as the escape of a noxious substance, or a fire)

Injuries

04/28/2023Chapter 9 10

• Minor injuries are small do very little harm to the body overall

• Some examples include: • Sprains and strains (swelling/bruising) • Cuts (requiring stitches or medical attention) • 'Simple' fractures and broken bones • Infections, skin irritation, and minor burns or scolds

04/28/2023Chapter 9 11

• Major Injuries: A major injury is something that can cause permanent damage to ones body. Often occurs in life threatening situations. 

• Some examples include: Stroke / heart attack Head injuries / unconscious Deep wounds i.e. stab wounds

"Minor" Injuries Can Become Worse

• You slipped on wet flooring in your office, but are sure you're OK. A few days later, you're experiencing serious back pain and can barely walk. This is an example of why reporting all workplace injuries is important; what may seem minor at the time can worsen, become chronic or lead to complications such as infection, disease or disability. Allow your employer to determine minor from major injuries and report any injury or illness occurring in your workplace. Failing to promptly report workplace injuries to your employer can void or reduce insurance or legal claims related to your injury.

The basic actions in an Emergency

Stay calm and assess the situation• Observe what has happened• Look for dangers to oneself and others• Never put oneself at riskMake the area safe• Protect any casualties from further danger• Remove the danger if it is safe to do so (i.e.

switching off an electrical current if an electrocution has occurred)

• Be aware of ones own limitations (e.g. do not fight a fire unless it is practical to do so)

04/28/2023Chapter 9 15

Assess all casualties to the best of ones abilities (especially if one is a qualified first aider)Call for help• Request help from those nearby if it is safe for them

to become involved• Call for local emergency

equipment (e.g. fire extinguisher)• Call for emergency services (ambulance or fire

brigade, etc.)Provide assistance as far as one feels competent to
