Whether safety procedures cause stress at workplace

Sometimes I hear shopfloor people grumbling at safety supervisors that by seeing them, B.P. increases in shopfloor workers. Others say that they are afraid that safety manager will come to them to enquire on some issue. Shopfloor supervisors advise safety persons not to approach their workers directly to avoid undue stress. All such talk or apprehensions appear to be unwarranted unless people do not follow safety procedures or the safety man talks in a dominating manner.
Some safety professionals too think that they get truth, if they pose like a  tough guy. But, with my own experience, I can say that this is not true. Whatever the shopfloor person is willing to tell will escape from the scene next time as soon as he sees the tough talking safety guy. The smooth talking safety supervisors also should be careful that they are not taken for granted. They have to develop friendly networks in all departments so that before entering the shopfloor to enquire about unsafe conditions or investigate accidents / incidents, full information is obtained through these friendly networks.
When someone gives information on phone, safety person should not insist to know the name of the person so that he will feel secured and will have peace of mind. If he is willing, then safety person can declare his sources and also recommend for some appreciation and reward.
Stress will be felt by safety guys also when all shopfloor people surround him questioning his failure to identify and communicate hazards. This, I think should be handled by being visible in the shopfloor through frequent inspections,giving pep talks as often as it warrants and making the people to know about their responsibilities under law. Then, safety department persons will be viewed as their friends and get their help to solve safety issues at the shopfloor.
Workers will be stressed for other reasons also as it was mentioned in a news paper article today that spouse causes more stress than the boss. Again, males cause more stress to their spouse than the female. Other reasons for stress can be ill health, unfulfilled ambitions,  family issues, etc
