This is a good letter but a few points:

There is a saying, You get more flys with honey - means if you are nice, then perhaps you will get what you want. Your letter is a little harsh.

Typically, in America, we would start the letter by saying who we are and provide our details. Then we would indicate the purpose of the letter, in this case, the concern for safety. Then we would suggest rememdies to the situation.
