When working with both feet on the ground it is still possible to obtain injuries by slipping, tripping and falling; anything above ground level is going to bring intrinsic risks. Per OSHA regulations, “Fall protection must be provided at four feet in general industry, five feet in maritime and six feet in construction.”
Risks are inherent in the activities we perform every day whether driving, flying, walking, or working. Every job has risks but some are riskier than others. If you are going to gamble, make sure it’s with money and not your life. Working at heights is a danger every day. No one should become complacent about it or think, “Oh, it’s not really that high.” Fall prevention was created for a reason and it won’t work if it’s not in use.
