Or rather, being cynical, the big chemical companies will lobby hard to prevent anything that may question the safety of their products. For example, how many years after the Manchester Woolworths fire was legislation brought in to control the type of foam used in furniture. Or how many years was it after smoking and cancer was linked before legislation limiting sales and advertising was introduced or closer to home, the use of thalidomide, first used in 1957 but it wasn’t until the early 60’s that it’s use was restricted despite evidence being there of its affects on unborn babies.
Like I say, maybe I’m just being cynical.
