Hazard Assessment • Implementing Response Objectives • Rescue • Public Protective Actions • Spill Control • Leak Control • Fire Control • Recovery
Lack of Control • Who was in control? • Fire Dept. • Hazmat • Railroad • Compliant? • IAP • Site Safety Plan
Basics Causes • Personal Factor • Education & Training • Inadequate equipment
Immediate Causes • Substandard Act/ Practices: • Reconnaissance • Hazard Assessment • Damage Assessment • Risk Assessment • PPE Selection
Incident/Event • Contractor using a torch
Loss • 5 Members injured • 3 critical • 2nd & 3rd burns • 2 treated and released • Delays • Clean-up • Commerce • Infrastructure
Why a Torch? • Couplings • Debris • Hot Tap
Hot Tap • Technique • Gain access • Liquefied gasses or liquids • Flaring vapors or liquids • Venting gases or vapors • Involves • Threaded nozzle • Welder • Specially designed drill • Valve
Hot Tap SOG • Note: This Guideline is one of many methods that could be utilized for the removal of products in the field. An evaluation of all methods shall be performed before choosing the method that suits the situation. • Note: This Guideline shall be used in conjunction with other Guidelines found in this manual i.e. Sit Safety Plan, Grounding and Bounding, Incident Action Plan etc.
Hot Tap SOG • Because of the possibility of burn-through or explosive decompression,a hot tap should not be used under any circumstances on tank car tanks containing the following products: • Bromine; • Chlorine; • Cryogenic liquids; • Elemental sulfur; • Ethylene; • Ethylene oxide; • Hydrocarbons in stainless steel tanks; • Hydrochloric acid; • Nitric acid; • Propylene oxide; • Sulfuric acid.
