Procedure No.: BC032.033 Page: 1 of 6 Preparer: Owner: Approver: OS/IH CoE Team Member OS/IH CoE Team Manager EHS Senior Vice President 1. PURPOSE The purpose of this document is to establish uniform pipe labeling requirements in alignment with Responsible Care and BASF Global requirements that will facilitate safe operation and emergency response. This applies to all chemical process piping containing hazardous materials including wastewater collection systems and utility systems where the utilities are hazardous by nature (asphyxiant, hot temperatures, high pressures). The recommendation is that this procedure be used as a best practice for all other piping. This does not apply to buried portions of pipeline, electrical conduits, process tubing, or fixed or portable hoses. 2. DEFINITIONS 2.1. Hazardous Materials Substances as defined by applicable national, regional, and/or local regulations that have physical hazards such as being flammable, combustible, explosive, oxidizing, self-reacting, pyrophoric, self-heating, or a substance which in contact with water emits flammable gases, organic peroxides, or materials corrosive to metal. Substances with health hazards such as being acutely toxic, corrosive or irritant to skin, serious eye damage/irritation, respiratory or skin sensitizer, carcinogen, mutagen, reproductive toxicology, target organ toxicity or aspiration toxicity or an asphyxiate; furthermore, to include substances that are hazardous to aquatic environments. Temperatures and pressures which when released from piping would have a potential for inflicting injury or property damage by burns, impingement, or flashing to vapor state. 2.2. OSBL (Outside Battery Limit) Process piping and utility piping that is not located in a production unit or designated block area and, generally, has multiple owners. Change of ownership on transfer and utilities lines (and the responsibilities therein) are per that site s definition. 2.3. Process Piping Process piping is a conduit, ¾ outside diameter and greater, for the transportation of gases, liquids, solids, or fine particulate dust. The word line or pipe has the same meaning for the purpose of this procedure.
Procedure No.: BC032.033 Page: 2 of 6 3. SCOPE This procedure applies to BASF Corporation and all of its subsidiaries in North America. This Procedure also applies to (i) BASF Canada Inc., its Canadian subsidiaries, and partnerships in which BASF Canada Inc. and/or its subsidiaries have a majority interest, (ii) DNA Landmarks, (iii) BASF Mexicana, S.A. de C.V. and BASF Interservicios, S.A. de C.V., and (iv) BASF de Costa Rica, S.A., BASF de Guatemala, S.A., BASF de El Salvador, S.A., BASF Dominicana, S.A. and BASF de Panama, S.A. de C.V. 4. PROCEDURE 4.1. General Labeling Requirements 4.1.1. Site Line Labeling Program If a site currently has a line labeling program and/or hazard communication program, the color schemes in use may be maintained provided the mandatory labeling and signage requirements listed herein are incorporated into the site s written program. In addition to these requirements, units/sites must also incorporate local and state labeling regulations as applicable. If a site has no labeling coloring scheme, the label color scheme in Table 1 is required. 4.1.2. Hazardous Materials - Piping All piping containing Hazardous Materials shall be labeled per this document. Identification of piping associated with utility systems is not required unless those systems are classified as hazardous. 4.1.3. Specific Labeling Information All labels must contain the following information: A. Hazard Information: Color code (see table 1), or Symbol, or phrase, or numeric rating (US NFPA Diamond) B. Direction of Flow Arrow C. Chemical Name (consistent with SDS Safety Data Sheet). C.1. Chemical name is exempt for: C.1.1. Batch / Campaign operations C.1.2. Piping internal to an existing continuous process that has a current labeling program that includes direction of flow and a hazard identifier and is located on a site that uses an onsite, offensive emergency response team. Note: Lines entering and leaving plant/block/cluster boundaries or entering and leaving a site, shall include the chemical name.
Procedure No.: BC032.033 Page: 3 of 6 4. PROCEDURE cont d. 4.1. General Labeling Requirements cont d. 4.1.4. Label - Hazardous Utility Services Label for hazardous utility services shall include the magnitude of service (e.g., 600 psi. steam,) and direction of flow. 4.1.5. Materials Used for the Identification of Piping All labels must withstand direct contact with hydrocarbons and process chemicals, operating temperatures up to 250 F and prolonged exposure to UV without deterioration and be guaranteed for a minimum of 5 years. The use of self-adhesive tapes and vinyl based products is not recommended. The recommended materials of construction for pipe identification: 5 mil (0.005 ) polyester and top laminated with a 2-mil (0.002 ) UV protective film. Markers should be pre-coiled and wrap entirely around the circumference of the pipe for piping up to 8 in outside diameter. Pipe markers for piping >8 in outside diameter should consist of the same printed 5 mil (0.005 ) polyester and top laminated with a 2-mil (0.002 ) UV protective film applied to a UV stabilized coextruded ABS plastic carrier. The carriers should be affixed to the piping using stainless steel straps. 4.1.6. Lettering for the Identity of the Hazardous Material The recommended font sizes for labels are provided in Table 2. All other text (e.g., hazard warnings) may be smaller font to fit the secondary information on the same label. 4.1.7. Label Maintenance Labels shall be maintained in a clear and legible state and shall be updated as necessary as process changes dictate. 4.1.8. Labels on OSBL Labels on OSBL process piping shall also indicate the owning department. This also applies to piping that passes through a unit or block that does not own the pipe.
Procedure No.: BC032.033 Page: 4 of 6 4. PROCEDURE cont d. 4.2. Location of Labeling 4.2.1. Labeling Safe Operation To ensure safe operation, pipe labeling is required at the following points of human interaction: A. Equipment Connections: One label shall be located at each entry and exit point from all equipment identified by an equipment number on the P&IDs. B. Block Valves: Lines shall be labeled once on the downstream pipe adjacent to the control valve. C. Battery Limits: Owner of the battery limit block valve is responsible for labeling the pipe at the block valve. D. Utility Stations: Label at the utility drop. E. Truck/Rail Load/Unload Locations: Labels shall be present at all truck and rail filling locations. Note: Multiple Criteria - when more than one of the criteria described above occurs on the same pipe at the same time, then a single marker shall suffice to identify the pipe. Example: If a tank, valves and pump are arranged within an approximate distance (a person can see all equipment, piping, valves from one fixed point), one label could be placed on the line coming from the tank and pump arrangement to identify the line content. 4.2.2. Label - Location on Piping Labels shall be located on the piping, so that one may see them in the normal line of vision (below or above the horizontal centerline). For OSBL and ISBL pipe racks, labels should be placed at distances that allow an individual to trace the line and identify its content.
