Terms. Accident Kickback Safety Hard Hat Hazards OSHA Safety Glasses

Potential Hazards in Forest Management Anytime that a person enters the forest there are hazards. Safety is an issue that should be of concern for any one involved in the forestry industry. Safe, well maintained equipment and tools are essential to maintaining a safe working environment. Emergency medical attention is seldom near by.

Some of the potential hazards are: A. Falling branches and trees B. Bees and hornets C. Stinging nettle, briars, and thorns D. Chainsaw kickback E. Poisonous snakes F. Operation of equipment on steep slopes G. Working in extremely hot or cold climates

Kickback Kickback is the sudden, unexpected upward and backward movement of the chain and guide bar. It occurs when the cutting teeth on the chain or the chain itself catches or binds in the cut. Because the chain is moving at very high speeds, if the chain or teeth strike a hard substance, or get pinched in the cut, the whole saw will move with great force. Anti-kick back bars should always been in place.

Kickback results!

Some ways to avoid kickback are: 1. Avoid cutting with the tip or upper quarter of the bar. 2. Use a tip guard that covers the end of the bar. 3. Operate the saw in the correct cutting position, stand at an angle to the saw so that if a kickback were to occur the saw would miss your head and neck.

Some ways to avoid kickback are: 4. Keep both hands on the saw while cutting. Keep your left elbow stiff. This will help prevent the saw from striking you should it kickback. 5. Don’t use a chainsaw to cut wood from old buildings, unless you are absolutely sure that all nails, screws, or other metal objects have been removed.

Safety Equipment Used in Forest Management II. There are many pieces of safety equipment that a forester should have on hand and know how to properly use.

Some of the basics are: A. Hardhat – A hardhat protects the forester’s head from falling limbs, branches, and even the fruits of some trees.

Some of the basics are: B. Safety glasses – These provide eye protection from low branches and shrubs when following a compass line. They also help keep shaving and saw dust out of the eye of a chainsaw operator.

Some of the basics are: C. Long-sleeved shirts – These are needed to provide protection to the skin from insect bites and from poisonous plants, such as poison ivy, poison oak, and poison sumac.

Some of the basics are: D. Heavy trouser or chaps – These items protect the legs from stinging nettle, briars, and thorns. Special chaps should be worn when operating a chainsaw to provide extra protection against injury.

Some of the basics are: E. High-top boots – This type of boot should be worn to provide good ankle support to reduce the chance of injury. Steel toes are recommended.

Some of the basics are: F. First-aid kit – A properly supplied first-aid kit should always be on hand when working in the forest.

Review / Summary 1. Identify potential hazards in forest management. 2. Identify safety equipment used in forest management.

Student Learning Activities Sample tests are available in the Lesson Plan tab.

Chain Saw Safety project. For this project have your students create a campaign about chainsaw safety. They can ether work in groups or by them selves, however you want them to work. Your students can make a video, poster, brochure, power point presentation, or anything else that they come up with. Have your students present their campaign to the class with minimum of a 5 minute presentation.
