Final answer:
When climbing a tree, essential safety gear includes a helmet, harness, gloves, and safety glasses, and measuring tape can be used to estimate the height of the tree. Precautions should be taken to ensure that no objects are dropped from height that could become hazards to people or cause damage.
Step-by-step explanation:
When preparing to climb a tree, safety is of utmost importance. You should be equipped with the appropriate gear to ensure your protection. It is essential to wear a helmet to protect your head from any falling objects or in case of a fall. As trees can be quite high, a harness is necessary to prevent falls. For your hands, gloves provide a better grip and protect against scrapes. Eye protection, in form of safety glasses, will guard your eyes against debris. Additionally, it is wise to have measuring tape handy to guess the height before climbing, ensuring you are aware of how high you will be ascending.
While working at such heights, it's important to take precautions to prevent objects from falling and becoming hazards. Always stay a safe distance from the edge and do not lean over railings excessively. Be sure that the area below is clear of people or vehicles and that dropping objects won’t cause damage. It is always better to be safe and take all necessary preventive measures before starting the climb.
