What are the 4 main hazards associated with running engines?

Why care should be taken with running engine in the automotive workplace?

Because carbon monoxide (from the vehicle exhaust) is heavier than air, the fumes may build up in the ‘confined space’ under the vehicle. These fumes need not be only from the vehicle being worked on: if other engines are running nearby, there is still a significant risk of exhaust emissions collecting in the pit.

Which precautions should you take when working on engine and exhaust hot components?

Wear gloves when handling hot engine components. Do not remove radiator cap unless engine is cold. Pressurized engine coolant may be hot. Do not touch hot exhaust systems, manifolds, engines, radiators, sample probe, or other hot parts.

How do you practice safe work with engine?

Safety standards

  1. All Engine Room Staff must be suitably dressed and must wear coveralls, safety shoes, gloves, goggles and helmets as per the VMS PPE matrix.
  2. Engine Room and machinery spaces must be kept clean, tidy and as free as possible from oil/fuel stains or sources, all of which must be identified and eliminated.

What is the danger of starting and running an internal combustion engine in an enclosed space?

Work done outside the space, but near openings to it, can contaminate the atmosphere inside the space. A common example is the exhaust gases from an internal combustion engine. There may also be potential for fire or explosion where hot work is done in areas next to confined spaces that contain flammable atmospheres.

What are the hazards associated with a running engine?

Working with vehicle engines can present a number of potential hazards, including contact with moving parts, electric shock, burns and carbon monoxide poisoning.

What are the hazards of a automotive workshop?

Some of the workplace safety hazards related to automotive workshops are obvious, such as vehicles falling from hoists or jacks, moving vehicles or tyres exploding during inflation. Other risks are less obvious, such as the long-term effects of exposure to asbestos fibres or fumes from solvents and paints.

What five 5 precautions should be observed if a vehicle is to be raised on a hoist?

Here’s what they advised.

  • Read the owner’s manual before you begin. …
  • Check the specific “lifting points” of the vehicle you’re working on. …
  • Never exceed your vehicle lift’s maximum capacity. …
  • Don’t rely on a single lift arm to bear all the vehicle’s weight. …
  • Choose an auto lift with automatic safety locks.

Why should you be careful when working with exhaust pipes and components?

The risk of the exhaust system coming into contact with combustible materials creates the potential to start a fire under the vehicle.

What precaution are needed when draining the engine oil from an engine?

Remember that the oil may be very hot, so avoid contact with it. Wait until no more oil drips from the drain hole, then clean the drain-hole threads and the surrounding area with a clean cloth or tissue. Clean the drain plug too, and make sure its washer or gasket is in good condition.

What are the most common hazards for an engine?

Mentioned below are ten such types of extremely dangerous engine room accidents that occur in ship’s engine room.

  • Crankcase Explosion of Ship’s Engine.
  • Over-Speeding of Generators.
  • Boiler explosion.
  • Compressor Airline Explosion.
  • High Pressure Fuel Line Bursting.
  • High Pressure Steam Leakages.
  • Turbo Charger Explosion.

What systems are needed to operate the main engine?

An evident decrease in the water level of the expansion tank indicates leakage. Slow turning of the engine must be carried out to prevent damage caused by fluid leaking into any of the cylinders. Permission from the bridge must be sought before turning the engine. Pre-lubrication should be carried out.
