A large number of gun safe manufacturers suggest that their gun safe is "DOJ approved". The point out of California Doj (DOJ) has required that any gun safe sold in California should be approved by the Regulatory Weapon Safe Standards. This DOJ standard has become a common rating for the classification of gun safes. However, in 2012, a study appeared in Forbes published by the investigative legal professional and physical security specialist Marc Weber Tobias, delivering the results of his investigation into the quality of the safety provided by eleven different types among three leading designs of marker safes sold in the U. S. through many retail outlets. Eight models in one of the brands are said to adapt to the DOJ standard. Tobias reported that this individual and his colleagues found that all eleven models could be opened with one of a variety of simple implements and techniques, including bouncing and rapping, or insertion of paperclips, wires, drinking straws, screwdrivers, or brass whitening strips that can be purchased from a hardware store. Four of the models were unlocked by a three-year old child. (It was a fatality causing from such an incident that led to the investigation. ) When Tobias reported their findings to the manufacturers and suppliers of the safes, no useful dialog or helpful action resulted. Tobias determined that the DOJ "Standards are woefully inadequate , nor address any of the issues that we found in any of the gun safes that we tested. If the Specifications do not cover a procedure for entry, then they are meaningless. Fireproof gun safes with regards to the build of the gun safe, the inside must not get warmer than a certain temperature during a certain period of time. One common rating for gun safes is "350-1 hour" or "350-2 hour", which means that when the safe is in a fireplace, the inside will not get more comfortable than 350 degrees Degrees fahrenheit for 1 or 2 hours. It is noted that fireproof safes may be insecure against unauthorized entrance.
