JOB HAZARD ANALYSIS

JOB: 

Snowmobile Operations

DATE: 7/3/01

PREPARED BY:      G.N. Delin

PAGE 1 OF 6 

REVIEWED BY:

Recommended Protective Clothing and Equipment: 

Snowmobile spare parts, PFDs, Two-way communications, snow shoes or skis, Snowmobile suit, and helmet with face shield.

Sequence of Basic Job Steps

Potential Accidents/Hazards

Recommended Safe Job Procedures

Obtain proper instruction before riding a snowmobile.

Personal injury, loss of life or loss or damage to equipment.

Prior to using a snowmobile in the field, experience in operating it must be gained.  Practice should be conducted in as open an area as possible before attempting rougher terrain.  When possible, training courses offered by local snowmobile associates should be employed.  Follow the manufacturer's operating manual for proper usage; always seek instruction from an experienced operator.

Test and inspect snow machine both physically and visually.

General nipping and pinching hazards, minor cuts and abrasions, possible inhalation or ingestion of fuel vapor/liquid.

Physically test and visually inspect all components including steering mechanism, motor, belts, throttle movement, lights, brakes and emergency switch and fuel status. Carry spare snowmobile parts where appropriate.

Transport snowmobile

Vehicle damage/loss due to insecure load or improper hitching of trailer. 

Personal injury or loss of life due to above.

All vehicle operators should acquire trailer towing experience by training in a large open area and under the direction of an experienced operator.  When possible, a driving safety courses should be taken by all staff required to operate a trailered vehicle.

Machines should be securely fastened at the front of the trailer with holding down rods through both skies just behind the forepart of the springs and at the rear with chains so there will be no forward, backward or lateral movement of the snowmobile while in transit.

See JHA on Trailering.

Remove snowmobile from trailer.

Strains/sprains due to improper lifting or manual handling of machine.

Minor cuts, abrasions, nips and pinch's.

Broken bones due to loss of control of machine.

Damage to equipment

The safest loading method for flatbeds is with a portable ramp, which aids in both loading and unloading.  Alternately a snow ramp can be build to the same height as the truck or trailer platform to eliminate lifting.

If lifting is required this can be done but only with three of four people available to help.

Always co-ordinate any work involving two or more individuals. This helps to eliminate unnecessary injury due to unplanned/unprepared lifting or carrying technique.

Conduct Pre-start Inspection.

Damage caused during transport resulting in loose fittings or inoperative controls, lights, etc.

Depress and release throttle control to insure cable operates freely.

Depress and release brake controls to insure free operation.

Conduct visual inspection to verify all nuts and bolts are tight and the hood is fastened securely.

Clear away any excess material from lights, running boards, seat, hood and windshield.

Make sure steering linkage is firm and handlebar moves freely.

Check belt drive for alignment.

Ensure track is clear and runs freely.

Check for sufficient fuel in the tank.

Check emergency stop switch for freedom of movement.

Suiting up

Improper/inadequate clothing.

Lack of helmet and/or goggles.

Lack of PFD if operations over water

Suiting-up should be done in layers.

• Porous or open basket weave thermal underwear provides body insulation and prevents air from being trapped close the body
• Second layer of clothing should be wool as this material keeps heat in and, with correct underwear, will not cause undue body moisture.
• Leather mitts with good wool liners are excellent for snowmobiling especially if they are the gauntlet type.
• Boots with a rubber lower half and nylon or leather upper half or all rubber boots are the most practical.  All boots should include felt liners for additional warmth and should be large enough to permit two pairs of socks to be worn.

Wear a snowmobile suit that is both windproof and waterproof with a lining that has a high-insulating factor (either one or two-piece).

Check the weather forecast and consult the Wind Chill Chart for the coldest weather you are likely to experience.

Helmets are mandatory and must conform to one of the acceptable standards.

Face shield protect the face and eyes from biting wind, tree twigs and other foreign matter.  Although goggles protect the eyes they have little protection for the rest of the face.  Tinted shields or goggles will greatly reduce the effects of bright sunshine off the snow.

Take along two-way communications and snowshoes or skis.

Proceed to site.

Careless or reckless driving.

Improper riding position

Unknown condition of trail/terrain, hidden obstructions.

Weather conditions.

Crossing of roads, railroads, bridges.

Driving while under the influence of any stimulant or drug is strictly prohibited.  In addition if the driver is unwell, for any reason, driving shall not be undertaken.

Balance is extremely important and is achieved by shifting body weight.  Leaning is the most frequent body shift used.

Maintain track contact with the snow/ground.  Shifting the body helps to achieve this goal.

When riding double, reduce speed to allow the passenger to shift weight at the same time and in the same direction as the driver.

Adopt the best position for driving;

Sitting is best for balance and control and is most comfortable for long rides

• Kneeing position is excellent in helping maintain balance when crossing the face of a hill
• Standing is really a high posting position used when better visibility is required such as climbing hills or when traveling over very uneven terrain.
• All three positions should be practiced a slow speeds in order to judge how best to maintain balance and control.

Maintain an awareness of the area being traveled.  Icy conditions call for special skills and sound judgment, as ice is foreign to good control.  Sharp changes in temperature cause lakes and rivers to form cracks.  The weight of ice on top of ice can cause it to throttle.

Hidden obstructions are sometimes buried just below the snow surface.  Use reduced speed on unfamiliar terrain.  When traveling in agricultural country operators must be alert for covered/buried fencing or closure chains.

Night riding and riding in stormy weather should be restricted as much as possible and done only in emergency situations.

Cross roads, railroads or bridges at right angles.  On roads motor vehicles have the right of way.  Railroad right of ways are private property, the suction created by a speeding train can cause sever and damaging injuries.  When crossing bridges and culverts keep to the extreme right hand and operate at low speed with extreme caution.

When possible, don't travel on ice-covered rivers or lakes.

Travel in a single file when using two or more snowmobiles. Stay about 50 feet apart while maintaining visual contact. The lead snowmobile operator should keep track of the trailing snowmobile.

Towing a cutter, toboggan or sleigh

Using improper tow bar.

Towing in improper area.

Not wearing proper PPE.

Equipment stowed improperly

All towing must be done by means of a rigid tow bar unless the reason is unditching a stuck vehicle or when an emergency rescue situation occurs.

At no time can a cutter, toboggan or sleigh be towed along a roadway.

The wearing of PPE (particularly helmets) is mandatory for operators, passenger and towed passenger or passengers.

When transporting equipment or supplies the gear should be kept low for greater stability.  It must be tied down securely.  When towing passengers avoid rough terrain, keep speeds moderate and execute turns slowly.  A snow flap (in good repair) should be mounted on the rear of the snowmobile to reduce the possibility of debris being thrown at the passenger(s).
