1 Try to arrange the outer interface of the tank at the end of the barrel at both ends because this part is not easily impacted;
2 The valve should be built-in as much as possible to reduce the part of the valve that protrudes out of the cylinder, to reduce or avoid impact;
3 The tank truck valve shall protrude from the cylinder part to have sufficient strength guardrail to protect the valve from impact;
4 Install a leak alarm on the tanker that is highly loaded and extremely hazardous to the toxic medium;
5 An emergency plugging device shall be added to tankers containing high and extremely hazardous toxic media, and emergency plugging measures may be taken in case of toxic media leakage.
