The pictogram on the label is determined by the chemical hazard classification. How Many Escape Routes Must A Workplace Have? Stopping safely is always a better option than steering off the road or into another lane. Additionally, if an escape route is longer than a certain minimum length (e.g., 18m in most UK buildings), applicable regulations may require it to be protected by fire doors and other fire protection equipment.
