Komatsu — Ventilation In Enclosed Areas

OM2034 10/04 General Safety - Section 20 Page 20-5 PRECAUTIONS DURING OPERATION Safety Is Thinking Ahead Prevention is the best safety program. Prevent a potential accident by knowing the employer's safety require- ments and all necessary job site regulations. In addition, know the proper use and care of all the safety equipment on the truck. Only qualified operators or technicians should attempt to operate or maintain the Komatsu Truck. Safe practices start before the operator gets to the equipment! Safety At The Worksite When walking to and from the truck, maintain a safe distance from all machines even if the operator is visible.

Before starting the engine, thoroughly check the area for any unusual conditions that could be dangerous. Choose an area where the ground is as horizontal and firm as possible before carrying out the operation. Examine the road surface in the job site and determine the best and safest method of operation. If you need to operate on a road, protect pedestrians and cars by designating a person for work site traffic duty or by installing fences around the work site. The operator must check personally the work position, roads to be used, and existence of obstacles before starting operations.

Always determine the travel roads in the work site and maintain them so that it is always safe for the machines to travel. If travel through wet areas is necessary, check the depth and flow of water before crossing the shallow parts. NEVER be in water which is in excess of the permissible water depth. Fire Prevention Thoroughly remove wood chips, leaves, paper and other flammable things accumulated in the engine compartment. These could cause a fire. Check fuel, lubrication, and hydraulic systems for leaks. Have any leaks repaired. Wipe up any excess oil, fuel or other flammable fluids. Be sure a fire extinguisher is present and in working condition.

Do not operate the machine near any flame. Preparing For Operation Always mount and dismount facing the truck. Never attempt to mount or dismount the truck while it is in motion. Always use handrails and ladder when mounting or dismounting from the truck. Check the deck areas for debris, loose hardware or tools. Check for people and objects that might be in the way. Become familiar with and use all protective equipment devices on the truck and insure that these items (anti- skid material, grab bars, seat belts, etc.) are securely in place. Ventilation In Enclosed Areas If it is necessary to start the engine within an enclosed area, provide adequate ventilation.

Exhaust fumes from the engine can KILL.
