Assignment #3: Flammable Liquid Storage
Objective: Students will be able to:
1. List five fire protection measures/control strategies that should be implemented for the storage of flammable liquids.
2. Complete a professional memorandum with necessary “talking points” for a presentation to convince management to implement their recommendations for the flammable liquid storage room.
Equipment: To complete this activity, the equipment listed below is needed:
· Access to 29 CFR 1910.106 and NFPA 30, and ANSI/AIHA Z10
· Case study description that includes a diagram of the building
Background: A common fire hazard in many general industry establishments and on construction sites is the storage and handling of flammable and combustible liquids. Ideally, the safety professional addressed these fire hazards during the design stage (prevention through design) and considered all risk reduction strategies (fire prevention and fire suppression).
Learning Through Discovery: Examine the existing standards in 29 CFR 1910 and NFPA 30 related to flammable liquid storage. You can also review the ANSI/AIHA Z10 standards as they relate to risk assessment and ranking.
Based on the information provided in Case Study 4-2 and Figure 4-3 (next page), complete the following table ( you can add or subtract rows based on the number of hazards you identify):
|
Flammable Liquid Storage Room Hazard |
Evaluation of Hazard (Applicable Standards) |
Hazard Ranking (per ANSI Z10 or other risk assessment) |
Control Strategies (Fire Prevention and Suppression) |

You will use the information from Case Study 4-2 and from the table you develop above to initiate the evaluation of risk. The case study and the diagram do NOT provide enough details to complete this evaluation. There are additional questions regarding the process/building that need to be answered so you can adequately assess the hazards and develop appropriate controls.
Some Additional Facts:
· Plan to operate the paint-dipping tanks 8-hours per day, 5 days per week
· Estimate that 200-gallons of paint and primer, and 40-gallons of thinner, will be used each week
· In the past 10 years, only one fire in the plant caused $500 in damage to the building from hot-work welding sparks igniting combustibles in shipping
· Management’s safety focus has traditionally been OSHA compliance and money
· The fire insurance representative will also be present at the manager’s meeting
· The height of the building is 20 feet
· Dollies will be used to handle the drums in the plant
· The average temperature inside the building is 65 degrees Fahrenheit
· The nearest property line to the building is 200 feet away
· The building is sprinklered throughout with a wet-pipe system
· Heating in the building is provided be radiant hot water in the ceiling
· Exterior walls are made of 12-inch concrete blocks, which have a 2-hour fire resistance, and the interior doors are rated at 1.5-hour fire doors
· All parking is in the front of the building
· The building has standard electrical circuits of 120 and 240, with the main electrical box located in the maintenance area
· Smoking is permitted only in a designated area outside
· Hazard Communication training is provided and SDS are available
· PPE provided to employees includes safety glasses and leather gloves for all employees, respirators for previous spray-paint operations, and leather chaps and welding helmets in the welding area
Learning by Doing: Based on all the information gathered during Learning Through Discovery, you will each prepare a professional memo with attachments and send it to the instructor, who will act as the plant manager in this case study. The memo should include an introduction explaining the purpose and the scope of the project and an overview of the fire hazards involved with the storage of flammable liquids. The attachments should include the following:
1. Completed table from Learning Through Discovery inserted in the memo and explained, and
2. Further explanation/detail of the recommendations related to control strategies – i.e., size of room, type of construction, ventilation, electrical system, sprinklers, detectors, cost, etc.
You will turn in: (1) the professional memo (including table and any further explanation/detail to support recommendations).
