Always wear protective gear
It’s general knowledge that whenever someone is climbing or working at high altitudes, he or she must have the necessary safety equipment. Otherwise, they could get injured or worse if they fall. A helmet, harness, protective gloves, and suitable footwear are types of protective gear to have on hand.
