# 3.5 Analysis: (cont.) ## 4. Backup Data (cont.) Place 50 mL of 0.1 M sodium sulfite and three drops of thymophthalein indicator into a 250-mL Erlenmeyer flask. Titrate the contents of the flask to a colorless endpoint with 0.1 N HCl (usually one or two drops is sufficient). Transfer 10 mL of the formaldehyde/methanol solution (prepared in 3.3.1) into the same flask and titrate the mixture with 0.1 N HCl, again, to a colorless endpoint. The formaldehyde concentration of the standard may be calculated by the following equation: Formaldehyde, mg/mL = ## acid titer X acid normality X 30.0 mL of sample This method is based on the quantitative liberation of sodium hydroxide when formaldehyde reacts with sodium sulfite to form the formaldehyde-bisulfite addition product. The volume of sample may be varied depending on the formaldehyde content but the solution to be titrated must contain excess sodium sulfite. Formaldehyde solutions containing substantial amounts of acid or base must be neutralized before analysis.

# 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 …

CCOHS CCHST Canadian Centre for Occupational Health and Safety Centre canadien d'hygiène et de sécurité au travail # Chemicals and Materials # Spill Response - Chemicals ## How can a workplace prepare for a chemical spill response? Most workplaces have products that are used and stored on their premises. Some may have a small amount (only a few litres of cleaning products, for example), while others may have significant quantities of chemicals in different physical forms. Each of these workplaces should develop and implement measures appropriate for the chemicals and quantity present. - Perform and maintain an accurate inventory of all chemicals in your workplace. - Use the information provided in safety data sheets (SDSs) and other technical data to identify the hazardous properties of the chemicals (e.g., flammable, corrosive, oxidant, reactivity with water, air toxicity). - Conduct a risk assessment. Identify the amount or size of the potential spills and the potential and severity to workers' health, the workplace, and the environment. - Based on the chemical's physical state (e.g., liquid or solid, including powders), determine the best methods to prevent, control, stabilize, and clean that spill. - Identify the materials, equipment, and personal protective equipment needed. The respiratory protection and protective clothing must be compatible with the chemical. Not all personal protective equipment will be compatible with all chemicals. - Develop a spill control procedure. - Make a spill response kit that contains chemical- or process-specific materials, the corresponding personal protective equipment, and other needed equipment. Make sure the kits are available near the work area and well-stocked at all times. - Train the workers to know the hazards of the chemicals they work with and how to respond to a spill. - Establish a spill response team as needed. Some useful standards to consult when developing a spill response plan include: - Nation…
