Sounds very suspicious to me... No protective gear required - but they died of exposure to toxic gas that does require protective gear. The main line tap was not closed off. The security guards refused entry to the police unit specifically designed to deal with this kind of situation. What else could possibly have gone wrong ?!?

Actually, hydrogen sulfide (H2S) is, believe it or not, more toxic than hydrogen cyanide (HCN), volume for volume. The main difference is that HCN (diffuse odor of bitter almond) normally is almost impossible to detect until it has totally poisoned the victim, whereas H2S (rotten egg odor) is detectable at much lower levels and those exposed can flee before they are fatally poisoned.

Typical Israel. Two people are dead the plant did not even shut down and if i was an employee i would not re-enter that place until some real procedures are in place. In america the place would be shut down until the investigation is over and than they would fix it before letting employees return. Well in Israel the investigation will go to the side and someone will pay them off and it will just go under the table. Poor men who died!!!!

Paz. Please care for their families

Detergent suicide, since it can be done at home by mixing cleaning/detergent products you buy at store. Won't give you an idea which ones though.
