Equipment and Installations (continued)

Exhaust Pipes

Cover hot exhaust pipes from engines (as well as stoves) with a solid or perforated metal shield.

Use a large metal plate or other non-flammable cover to prevent hot exhaust pipes from setting fire to the deck.

Ventilation and Backfire Control

Many fires and explosions are caused by poor ventilation or backfire control.

For proper ventilation:

Use at least one exhaust duct leading from the bilges, under the engine, to the surface.
Use at least one supply duct from the surface to a level below the engine air intake.
Place ducts far apart for good circulation.
Ducts may be fitted with wind-activated, self-trimming or rotary heads as well as power exhaust fans.
Turn on the fan at least 5 minutes before starting the engine.

Flame arrestors help prevent dangerous backfires. Clean them often with soap and water.
