An explosive tool is disclosed. The explosive tool comprises a body structure, a charge, a detonator to ignite the charge via propagation of thermal energy, a pressure actuated safety to prevent propagation of sufficient thermal energy to ignite the charge when the pressure actuated safety is subjected to a surface pressure and to not prevent propagation of sufficient thermal energy to ignite the charge when the pressure actuated safety is subjected to at least a predefined pressure threshold, and a temperature actuated safety to prevent propagation of sufficient thermal energy to ignite the charge when the temperature actuated safety is subjected to a surface temperature and to not prevent propagation of sufficient thermal energy to ignite the charge when the temperature actuated safety is subjected to at least a predefined temperature threshold. The charge, the detonator, the pressure actuated safety, and the temperature actuated safety are contained within the body structure.
