Safe Use of gasoline chain saws: International standards and Best Practices

As a powerful tool, gasoline chain saws are widely used in logging, garden maintenance and building construction. However, due to its high-speed rotating chain and powerful power, improper use may lead to serious safety accidents. It is therefore essential to understand and comply with international safety standards and best practices. This article will introduce the safe use of gasoline chain saws in detail, including pre-operation inspection, correct operating posture, emergency treatment, etc., to help users use gasoline chain saws safely and efficiently.

First, check before operation
1. Check the safety equipment
Before using a gasoline chain saw, ensure that all safety equipment is complete and functional. This includes, but is not limited to:
Recoil guard: Ensure that the recoil guard is working properly to prevent the chain from accidentally starting.
Chain brake: Check whether the chain brake can stop the chain quickly, which is a key safety device to prevent accidents.
Oil lock: Make sure the oil lock is functioning properly and the chainsaw will only work when a specific button is pressed.
2. Check the mechanical parts
Chain tension: Ensure that the chain tension is moderate, neither loose nor tight.
Guide plate installation: Check whether the guide plate is properly installed and is not loose or damaged.
Engine operation: Check whether the engine can start and run normally without abnormal noise or vibration.
3. Check fuel and lubricating oil
Fuel quality: Use unleaded gasoline above 90, and ensure that the fuel is clean and free of impurities.
Lubricating oil: Ensure that chain lubricating oil is sufficient to reduce chain wear.

Second, correct operating posture
1. Use both hands
Always hold the chain saw firmly with both hands, with the thumb and fingers firmly holding the handle to reduce recoil.
2. Hold a steady position
Stand on your feet: Keep your feet shoulder-width apart and balance.
Bend your knees slightly: Bend your knees slightly, keep your back straight, and avoid bending over for a long time.
3. Avoid dangerous movements
Avoid one-handed operation: One-handed operation reduces control and increases the risk of accidents.
Avoid overstretching: Avoid overstretching your body to avoid losing your balance.

Third, emergency handling
1. Stop the chain saw
In case of emergency, quickly press the stop button so that the chain saw stops running immediately.
2. Evacuate dangerous areas
If an accident occurs, such as a fallen tree or a broken chain, evacuate the danger area immediately and ensure the safety of those around you.
3. First aid measures
Wound management: If cutting wounds occur, stop bleeding immediately and seek medical attention as soon as possible.
Fire treatment: In case of fire caused by fuel leakage, fire extinguishers should be used immediately.

Fourth, international safety standards
1. ISO 13772:2018
The standard specifies performance requirements, test methods and standardized operating procedures for non-manually operated chain brakes to ensure the safe use of chain saws by forest workers.
2. ANSI B175.1-2012
This standard, developed by the American National Standards Institute, covers safety requirements for the manufacture and use of portable, hand-held, gasoline-powered chain saws.
3. CSA Z62.1-15 (R2020)
The standard revises the safety of chainsaws, references new IEC, ISO and USDA standards, and harmonizes the text of this standard with international standards, where appropriate.

Fifth, daily maintenance and maintenance
1. Cleaning and inspection
Clean the chainsaw: After each use, the surface and heat sink of the chainsaw should be cleaned to ensure good heat dissipation.
Check the wear of the chain: check the wear of the chain regularly and replace it in time if necessary.
2. Lubricating oil replacement
Change the lubricating oil regularly to ensure that the engine and chain are well lubricated.
3. Air filter maintenance
Clean or replace the air filter regularly to keep the engine in good running condition.

The safe use of gasoline chain saws is not only about the personal safety of the operator, but also affects the safety of the surrounding people and the environment. By adhering to international safety standards and best practices, such as thorough pre-operation inspections, proper operating posture, proper handling of emergencies and routine maintenance, the risk of accidents can be significantly reduced and the efficient and safe use of petrol chain saws can be ensured.
