<human>:  What type of safety precautions should I take while using a chainsaw?
<bot>: When using a chainsaw, it is important to take safety precautions such as wearing protective eyewear and clothing, using hearing protection, keeping the saw lubricated and in good repair, having the right kind of saw for the job, never cutting with a dull blade, and never working alone. Additionally, it is important to be aware of your surroundings and be careful not to strike a hard object, which can cause the saw to kick back and cause serious injury. Lastly, make sure you know how to properly use the saw, including starting it safely, following all the manufacturer's instructions, and not operating the saw when tired or under the influence of drugs or alcohol.
