Carelessness or negligence is not always the reason behind the Human error. In some cases, the desire for extra speed increased production & making task easier mean guards are bypassed or removed. Workers may become bored and distracted with repetitious work or use unsafe work practices to overcome poor plant design. For example, locating two important operator controls close together which are of similar shape or size may lead to the user mistakenly operating the wrong control. Workers have a responsibility to take reasonable care for their own health and safety and must not adversely affect the health and safety of others. Workers must comply with any reasonable instruction and co-operate with any reasonable policy or procedure. Workers should not use unsafe practices or deliberately bypass guarding on the plant.
