Answer:
D) When employers cannot provide safety training
Explanation:
It is very important to protect our self. The very first which needs to be considered is that all employers must know A to Z of the safety training. Those who are given the training for the work, should be given the training regarding the safety as well at the very same time by the employers.
It should be given to all the employees irrespective of the department which they belong to. Their families will also be safe if they learn about safety training. So considering from safety point of view, if employers are unable to provide safety training, they should atleast provide them with personal Protective Equipment.
