The top of a 332 is a long way to fall and I personally know of 2 engineers who have misjudged handholds and slipped. One died and the other sustained a fractured skull and it still off work.
If you can think of another form of protection then suggest it to the company. Otherwise I am afraid that in today's 'Elf and Safety conscious 'Target Zero' work environment you will just have to accept it.
