Bulk Storage of Flammable and Combustible Liquids Standard

PS-ST-001Global Supply Chain

PROCESS SAFETY WARNING – If Printed this document becomes an UNCONTROLLED Copy

I. POLICY

This standard outlines the Ecolab corporate requirements for the safe bulk storage of flammableand combustible liquids in bulk storage systems. The standard is based on NFPA 30 Flammable and Combustible Liquids Code. NFPA 30 provides greater detail and guidance and should be referred to for interpretation of this standard.

1. Requirements in this document are identified as follows:a. Mandatory requirements are identified by the bolded terms “shall” or “must”;b. Recommendations, identified by the terms “recommended” or “should”, are

not mandatory but preferred options. Each site is expected to follow recommendations where possible; and

c. Guidance, identified with the terms “suggested” or “may”, is given where a specific approach cannot be defined or where multiple options are acceptable.

2. These requirements apply to all new construction and modifications to existing facilities.

3. These requirements do not apply retroactively to existing situations unless identified in the following manner: *** (Applies retroactively at all Ecolab sites)***.

4. It is recognized that standards cannot cover all possible situations and good engineering judgment may dictate alternative arrangements. Alternative arrangements for mandatory requirements must be approved, see PS-XX-NNN: Exception Process.

5. In the event of a conflict with government or local standards, codes, or regulations, then the more stringent of the two (regulation or the Ecolab standard) must be followed.

6. In the event of a conflict with any legacy company standard, guidance document or commonly accepted practice, the requirements in this standard must be followed.

II. SCOPE

This standard applies to the bulk storage of flammable and combustibleliquids at all Ecolab and Nalco Champion manufacturing, processing, blending, and storage locations globally.

Storage, processing, handling and use of Class II and Class III liquids heated to within 17 degrees C of their flash point shall be treated as Class I liquids unless an





engineering evaluation conducted in accordance with NFPA 30 justifies following the requirements for another liquid class.

III. DEFINITIONS

1. Flammable liquids shall be classified as Class I liquids and further sub classified according to the following

a) Class IA Liquid- Any liquid that has a flash point below 22.8 deg C and a boiling point below 37.8 deg C

b) Class IB Liquid- Any liquid that has a flash point below 22.8 deg C and a boiling point above 37.8 deg C

c) Class1C Liquid- any liquid that has a flash point at or above 22.8 deg C but below 37.8 deg C

2. Combustible liquids shall be classified in accordance with the following

a) Class II liquids- Any liquid having a flash point at or above 37.8 deg C and below 60 deg C.

b) Class IIIA Liquids- any liquid having a flash point at or above 60 deg C but below 93 deg C

c) Class IIIB Liquid- Any liquid having a flash point at or above 93 deg C.

B. Bulk Storage Systems-Bulk storage systems are defined as fixed tanks that exceed 230 L in capacity, portable tanks that exceed 2500 L in capacity or intermediate bulk containers that exceed 3000 L

C. Flash point- The minimum temperature of a liquid at which sufficient vapour is given off to form an ignitable mixture with air, near the surface of the liquid or within the vessel used.

D. Boiling point- the temperature at which the vapour pressure of the liquid equals the surrounding atmospheric pressure.

E. Unstable Liquid-Aliquid that, in the pure state oras commercially produced or transported, will vigorouslypolymerize, decompose, undergo condensation reaction or become self-reactive under conditions of shock, pressure or temperature.

F. Boil Over-An event in the burning of certain oils in anopen-top tank when, after a long period of quiescent burning,there is a sudden increase in fire intensity associated with expulsion of burning oil from the tank.
