I think the relevant point here is not about safety issues, it's more about using the right method.
My interpretation of the original post was that there was some sort of safety essay request; the OP used his safety essay to point out flaws in the company's safety system. If this safety essay was to be a corporate PR sort of thing, then his response was not what was wanted.
If your boss wants a nice fluffy safety piece written, for example, for the company newsletter, then pointing out deficiencies will not win you friends.
For those married forum members, if your spouse asks 'How does this look on me, dear?', the advisable response is not, 'Well, you know, you could lose a few pounds, and tighten up those abs'.
