HazCom Chemical Hazard Communication in the Mining Industry
What is a hazardous chemical? Any chemical that presents a physical or health hazard For example: Liquids (diesel fuel) Solids (coal or silica dust, welding fumes) Gases (NO 2 from blasting)
What do I have to do? l Inventory determine l Inventory the chemicals at your mine & determine which are hazardous Written Program l Have a Written Program Labels & MSDSs l Have Labels & MSDSs l Train l Train your miners access l Allow access to HazCom info
What do I have to do? l Inventory determine l Inventory the chemicals at your mine and determine which are hazardous.
How can you determine which chemicals are hazardous? HAZARDOUS If it says HAZARDOUS on the label or MSDS, or If stated in an MSHA standard, or If listed in - ACGIH “Threshold Limit Values” (2001 edition), - National Toxicology Program (NTP), or - International Agency for Research on Cancer (IARC), or Use laboratory test results or other evidence
A chemical may be: m a physical hazard -a chemical is a physical hazard if it has the potential for fire, explosion or reactivity
A chemical may be: m a physical hazard m m a health hazard acute chronic
A chemical may be: m a physical hazard m a health hazard m m both a physical hazard and a health hazard
A chemical may be: m a physical hazard m a health hazard m both a physical hazard and a health hazard a health hazard m m neither a physical or health hazard
A chemical may be: m a physical hazard m a health hazard m both a physical hazard and a health hazard a health hazard m neither a physical or health hazard hazard m m exempt from HazCom
Chemicals exempt from HazCom 1. Consumer Products – – consumer packaging, used as intended, no exposure beyond ordinary consumer use
What about chemical mixtures produced at the mine? If tested as a whole... use the results of the test If NOT tested as a whole... physical hazard physical hazard: use valid scientific evidence health hazard health hazard: assume same health hazard as any 1% component and cancer hazard cancer hazard: assume same as any 0.1%. cancer component per NTP, IARC.
What do I have to do? written l Establish a written HazCom program. XYZ Mining Co. HazCom Program Manual
Your written program must include: m How you determine which chemicals at your mine are hazardous LIST m A LIST of the hazardous chemicals at your mine
Your hazardous chemicals LIST must: list labelMSDS m Use a chemical identity that permits cross-referencing between the list, a chemical’s label, and its MSDS; and m Be compiled for the whole mine or individual work areas.
Your written program must include: m m Where you keep an MSDS for each hazardous chemical; m m How you will tell miners about unlabeled chemicals (in pipes, for example) and the hazards of jobs that are not routine;
Your written program must include: m How you will inform other on-site operators about your chemical hazards and the protective measures their employees need. m m What training you will give miners & when;
Your written program must include: m What labeling system you use; that is, how you will label containers.
What do I have to do? Labels & MSDSs l Have Labels & MSDSs brought toproduced at for hazardous chemicals brought to & produced at your mine
Labels must: m Be in English, readable, and obvious. m Have a chemical’s name as it appears on the MSDS & your list. m Contain appropriate hazard warnings (“words, pictures or symbols that convey the specific physical and health hazards”) m Be on all containers of hazardous chemicals - unless exempt
Label Alternatives (stationary process containers) m May use sign, placard, process sheet, etc. if it: – identifies the container it applies to; – has the same information as the label; and – is immediately accessible to miners.
Labeling l You must: –Immediately replace a label if missing or marred. –Not remove or deface any label. PRODUCED –Prepare a label for each hazardous chemical PRODUCED at the mine -- & update it with new significant info within 3 months of learning of it. BROUGHT –Replace obsolete labels when received for each hazardous chemical BROUGHT to mine.
Label-Exempt Containers include: m PORTABLE TEMPORARY m PORTABLE TEMPORARY containers, when used during one shift by person who transferred the chemical m RAW MATERIAL m RAW MATERIAL containers such as - a feed hopper at your primary crusher, or wash tanks for your sand plant. OTHER LABELING LAWS m Containers subject to OTHER LABELING LAWS (e.g., USDA, EPA, Consumer Product Safety Act)
Material Safety Data Sheets (MSDS) l You must: –Have an MSDS for each hazardous chemical you use. PRODUCED –Prepare an MSDS for each hazardous chemical PRODUCED at the mine. BROUGHT –Replace outdated MSDS for each hazardous chemical BROUGHT to the mine. MSDS 1. Chemical Identity 2. Chemical Properties 3. Physical Hazards 4. Health Hazards 5. Exposure Limits 6. Carcinogenicity 7. Safe Use 8. Control Measures 9. Emergency Info 10. Date Prepared
MSDSs must be: m Current, legible, accurate and in English m Readily accessible to miners where they can be exposed (centralized or at each work station) chemical identity m Cross-referenced to your LIST & LABEL by chemical identity used m Retained m Retained for as long as the chemical is at the mine, & for 3 months after notifying miners of its pending disposal
Material Safety Data Sheet (MSDS) HAZARDOUS WASTE l If you cannot obtain an MSDS for HAZARDOUS WASTE, you must give each potentially exposed miner access to any MSDS information that is available, such as –Hazardous components, –Physical or health hazards and –Protective measures.
MSDSs must contain: 1. Identity 2. Physical / Chemical properties 3. Physical Hazards 4. Health Hazards 5. Carcinogenicity 6. Exposure Limits 7. Safe Use 8. Control Measures 9. Emergency Information 10. Date Prepared
MSDSs must contain: 1. Identity: –The chemical and common name if it is a single substance and those of the hazardous ingredients if it is a mixture.
MSDSs must contain: 2. Properties: –The physical and chemical properties, such as boiling point, melting point, vapor pressure, evaporation rate, solubility in water, pH, appearance and odor, flash point and flammability limits.
MSDSs must contain: 3. Physical Hazards: – The potential for fire, explosion, and reactivity.
MSDSs must contain: 4. Health Hazards: –The potential to cause an illness or injury, such as its acute and chronic health effects, the signs and symptoms of exposure, any medical conditions that are aggravated by exposure and the primary routes of entry.
MSDSs must contain: 5. Carcinogenicity: –The carcinogenic classification, if any, such as whether the chemical is a potential, probable, or known human carcinogen.
MSDSs must contain: 6. Exposure Limits: –Such as MSHA's, OSHA's, ACGIH's TLV, or NIOSH's REL.
MSDSs must contain: 7. Safe Use: –Any precautions for safe use, such as appropriate hygienic practices, protective measures during repair and maintenance of contaminated equipment, and procedures for clean-up of spills and leaks.
MSDSs must contain: 8. Control Measures: –Such as ventilation, process controls, restricted access, protective clothing, respirators, and goggles.
MSDSs must contain: 9. Emergency Information: –Emergency procedures, such as special instructions for firefighters and first aid procedures; and the name, address, and telephone number of a contact person who can provide additional information about the hazardous chemical and the emergency procedures.
MSDSs must contain: 10. Date Prepared: –The preparation or revision date of the MSDS.
What do I have to do? Train your miners about the HazCom program and the hazardous chemicals they can be exposed to.
HazCom Training includes: m The physical and health hazards of the chemicals in the individual’s work area; m The requirements of HazCom;
HazCom Training includes: m The mine’s HazCom program, including an explanation of the labeling system, the MSDSs, and how they can get the information and use it;
HazCom Training includes: m Where HazCom materials (labeling information, the list of chemicals, and the MSDSs) are kept and that they’re available; m The operations or areas of the mine where hazardous chemicals are present;
HazCom Training includes: m How to tell if a chemical is present or if there’s been an inadvertent release (smell, color, etc); m m What protective measures to take; and
HazCom Training includes: m The work practices, engineering controls, emergency procedures, and use of personal protective equipment the mine uses to protect miners from hazardous chemical exposures.
What do I have to do? l Allow your miners to look at the HazCom information you have and give them a copy of it if they ask.
Access To HazCom Information m Must be provided to: –Miners –Their designated representatives –MSHA –NIOSH
Trade Secrets l Companies may request that MSHA provide protection of certain chemical information as a trade secret. l l MSHA will determine if information qualifies as a trade secret.
Trade Secrets l The identity of a trade secret must be disclosed immediately to health professionals in a medical emergency.
