1. A containment system for hazardous products, the system comprising:
a housing unit having compartments for storing different ones of the hazardous products therein, each of the hazardous products being a battery;
a first fire suppression system having tubing for releasing a fire suppression material into the housing unit during a thermal event of one of the hazardous products;
a second fire suppression system configured to suppress the thermal event; and
a venting system configured to release the heat from the thermal event from one or more of the compartments, the venting system including one or more of a passive venting system having a valve that releases the heat or an active venting system,
wherein the second fire suppression system comprises an intumescent material disposed on one or more surfaces of the compartments in the housing unit; and
wherein the intumescent material is configured to begin expanding within the one compartment as a direct reaction to the heat from the thermal event before the fire suppression material begins to be released from the tubing into the one compartment, and wherein the venting system is configured to begin releasing the heat from the thermal event before the intumescent material begins to expand.
