# Battery Charging - Industrial Lead-Acid Batteries (cont.) ## Are there any other hazards involved? (cont.) Depending on the metal alloy composition in lead-acid batteries, a battery being charged can generate two highly toxic by-products. One is arsine (arsenic hydride, AsH3) and the other is stibine (antimony hydride, SbH3). Generally, the air levels of these metal hydrides tend to remain well below the current occupational exposure limits during battery charging operations. Overcharging a lead acid battery can also lead to the generation of hydrogen sulfide, which can cause harm to workers if exposed. Although these risks may be minimal when batteries a properly charged, their possible presence re-enforces the need for adequate ventilation systems. In addition, always follow the manufacturer's recommend charging time and only use manufacturer-approved charging devices appropriate for the voltage and amp-hours (ah) of the battery. ## How should industrial size batteries be handled? Industrial batteries (e.g., forklifts or battery powered industrial trucks) may weigh up to 900 kg (2,000 lbs) or more. Workers must be trained in how to safely move batteries using appropriate equipment (e.g., specially equipped forklift, battery cart, conveyor, overhead hoist, etc.) - Batteries must be securely placed and restrained. - Use only the appropriate tools and follow safe work procedures.

# Battery Charging - Industrial Lead-Acid Batteries (cont.) ## Why is it important to follow safety procedures when charging batteries? (cont.) NOTE: This OSH Answers document provides general guidance for industrial lead-acid batteries used to operate forklifts and is not meant to replace the requirements from the manufacturer or legislation. ## What are the risks of charging an industrial lead-acid battery? The charging of lead-acid batteries (e.g., forklift or industrial truck batteries) can be hazardous. The two primary risks are from hydrogen gas formed when the battery is being charged and the sulfuric acid in the battery fluid, also known as the electrolyte. Hydrogen gas can lead to fires and explosions, and worker exposure to sulfuric acid can lead to chemical burns and other adverse health effects. Improper handling of batteries can also lead to shocks and electrocution, and battery charging can also result in the release of other harmful contaminants. For general safety precautions when working with batteries, please see the OSH Answers Garages - Batteries which covers automotive vehicle sized batteries and the OSH Answers on Forklift Trucks - Lead-Acid Batteries for forklift batteries. For specific guidelines regarding large industrial batteries, check with the manufacturer for recommended safe work procedures. ## Why is there a risk of an explosion? When leac-acid batteries are being recharged, they generate hydrogen gas that is explosive in certain concentrations in air (explosive limits are 4.1 to 72 percent hydrogen in air). The ventilation system needs to be able to exchange an adequate amount of fresh air for the number of batteries being charged. This is essential to prevent an explosion. Batteries should also not be charged or handled near sources of heat, flames or sparks, such as welding activities, burning cigarettes, or other source of ignition. Charging stations for battery-powered industrial trucks, per the National Fire Code of Can…

# Spill Response - Chemicals (cont.) ## How can a workplace prepare for a chemical spill response? (cont.) American Society for Testing and Materials (ASTM) Standard Guide for Using Aqueous Foams to Control the Vapor Hazard from Immiscible Volatile Liquids (USA) ## What should a chemical spill control procedure include? A spill control procedure should define and establish the following: - Definition of what that workplace considers to be small and large spills, including the types of spills that can be handled internally versus the spills that a specialized spill response team should handle. Generally speaking: - A small spill is one that is of a limited quantity, does not spread fast, and does not place workers, the workplace, or the environment in danger. - A specialized spill response should be used where there is a risk of fire or explosion or the chemical is highly toxic. - Who is to respond to the spill and their contact information - Spill prevention measures to be followed. These measures may include using double-wall tanks, secondary containment, and following safe handling and storing procedures. - Instructions on how to control spills of specific chemicals, and when safe to do so. - The appropriate method to reduce the hazard of the spilled chemical (e.g., stabilization, neutralization, dilution, etc.). - Clean-up procedures. - Area decontamination procedures. - How to dispose of the contaminated materials. These materials should be disposed of according to local regulatory requirements for environmental protection. - First aid procedures. - List of appropriate personal protective equipment (PPE) - Decontamination procedures for the personal protective equipment (PPE), as appropriate - Reporting procedures for all spills and near-misses, such as to a specified person or department, or the health and safety committee. - Determine which spills must be reported to local authorities, especially if the spill has leaked into the drains or …

# Forklift Trucks - Batteries (cont.) ## Why is it important to follow safety procedures when charging batteries? (cont.) NOTE: This OSH Answers document provides general guidance for industrial lead-acid batteries used to operate forklifts and is not meant to replace the requirements from the manufacturer or legislation. ## Why should you follow safety precautions when charging batteries? Lead-acid batteries contain sulfuric acid. Only trained and authorized personnel should handle them. When talking about lead-acid batteries, people usually call sulfuric acid "battery acid" or the "electrolyte". An electrolyte is a general term used to describe a non-metallic substance like sulfuric acid or salts that can conduct electricity when dissolved in water. Lead-acid batteries can produce explosive mixtures of hydrogen and oxygen gases when they are being charged. Note that in some cases, hydrogen gas has been found to interfere with carbon monoxide detectors. Check with your detector manufacturer(s) for more information. - Charge batteries only in approved, well-ventilated battery-charging areas. - Install a safety shower and an eyewash station in a battery-charging area. - Always follow the manufacturer's instructions for safely charging the battery. ## What are some precautions to use when watering a battery? During the normal operation of a forklift with a flooded lead acid battery, the water in the electrolyte evaporates and needs to be refilled (watered) to keep the battery operating effectively and safely. - Develop procedures based on the manufacturer's instructions on how and when to water the battery. - In general, a battery should be watered after it has been fully charged and cooled down. - Do not water a battery before or during charging, as the water may boil over and cause acid to leak. - Use distilled water (not tap water) to refill the electrolyte. - Never add sulfuric acid to the electrolyte. - Wear appropriate personal protective equipme…

# Battery Charging - Industrial Lead-Acid Batteries (cont.) ## What are the ventilation requirements for charging areas? (cont.) Many standards and codes recommend a ventilation system that prevents the accumulation of hydrogen to above 25% of its lower explosive limit (LEL), or above 1% by volume. Guidelines for ventilation in battery charging areas, based on the National Fire Protection Agency Standards (NFPA 855), are provided below: Natural exhaust ventilation: designed to limit the concentration of flammable gas to 25% of the lower explosive limit (LEL) during the worst-case scenario of charging all batteries at the same time. Mechanical Ventilation: an exhaust ventilation rate that is effective at limiting the maximum concentration of hydrogen to 1% of the total volume of the room or area during a worst-case scenario when all batteries are being charged at the same time. Alternatively, having a ventilation rate based on the area of not less than 1ft3 / min / ft2 of the floor area of the room. ## Why can you get a burn from acid when handling the batteries? You can get a skin burn when handling lead-acid batteries. Sulfuric acid is the acid used in lead-acid batteries (electrolyte) and it is corrosive. Note: workers should never pour sulfuric acid into flooded lead acid batteries (included in new watering a battery section). If a worker comes in contact with sulfuric acid when watering a battery or when handling a leaky battery, it can burn and destroy the skin. It is corrosive to all other body tissues. For example, the eyes, respiratory tract, or digestive system can be harmed severely if a worker gets a splash in the eyes, inhales sulfuric acid mist or unintentionally ingests sulfuric acid. As with any corrosive chemical, appropriate handling procedures must be followed to prevent contact with the liquid. These procedures include the wearing of face and eye protection, and protective chemical- resistant clothing such as aprons and gloves that are suita…
