Decanting Chemicals
Job Hazard Analysis
Facility: Science Department Approved by: Science Dept. Date Revised: June, 2019 Step Description Hazard Controls 1 Read the label on the chemical to be decanted 2 Locate MSDS and read precautions listed. 3 Locate PPE as per MSDS Personal protective equipment (PPE) should include whatever is specified on the MSDS. Generally, an apron, goggles and gloves are required. 4 Using a funnel, pour the chemical from the large container to the small container Muscle Strain Back Injury Contact with skin Inhalation of vapours Assess muscle strength-- Follow established procedures for lifting. Work in a fume hood if hazardous vapours are present. 5 Make sure small bottle has a proper workplace label applied, using data from the MSDS sheets
Decanting Chemicals
SAFEWORK Procedures
Facility: Science Department Approved by: Science Dept. Date Revised: June 20, 2016 Hazards Present: Personal Protective Equipment (PPE) or Devices Required: Additional Training Requirements: Spillage of chemical, resulting in burns to skin, damage to eyes. Inhalation of vapours Strain to back Lab coat or safety apron Safety gloves – should be non- slip. Disposable gloves are okay Safety goggles or face shield Lifting of heavy objects if the original container is quite large. Chemical clean-up procedure
SAFEWORK Procedures
1.) Place the new container on a level surface at about waist height. If the MSDS suggests that the chemical is volatile or produces harmful vapours, all work must be done in an approved fume hood. 2.) Select an appropriately sized funnel for the job. Larger containers will require larger funnels. 3.) Support the funnel in a proper holder, using a ring stand and clamp or similar device. 4.) Carefully support the original container in both hands, holding it so that on tipping, the mouth of the container is a few inches about the height of the funnel. 5.) Pour the chemical slowly into the funnel, not allowing the level of the liquid to rise closer than one inch from the top of the funnel. 6.) Stop before the second container becomes too full, to allow emptying of the funnel without overflow. Note : If the purpose of the transfer is to create a diluted stock solution of a corrosive chemical, always start the transfer after having placed about one-half of the required water into the receiving container.

Chemical Spills
SAFEWORK Procedures
Facility: Science Department Approved by: Science Dept. Date Revised: June 20, 2016 Hazards Present: Personal Protective Equipment (PPE) or Devices Required: Additional Training Requirements: Contact of chemical with skin or clothing Inhalation of vapours Appropriate spill clean-up kit Apron or lab coat Gloves Goggles or face shield
SAFEWORK Procedures
Note : The following procedures are for controlling and cleaning spills that are determined to be safe for disposal with the provided spill clean-up kits. If the spill is determined to be of substantial danger as a result of excessive vapours or other concerns, evacuate the school and contact the fire department. 1.) Remove all students from the immediate area, or from the room, if necessary. 2.) Designate one student or an E.A. to obtain the appropriate spill clean-up kit – acids , caustic , flammable. Refer to the procedures provided within the spill clean-up kit. 3.) Put on goggles, gloves and apron. 4.) Working from outside the spill area, lay out the dam so that it completely surrounds the spill. 5.) Apply absorbent pads to soak up spill. If the area is large, use a metre stick or other reaching aid to help position the pads. Wait until the pads have soaked up the spill. 6.) Collect absorbent pads and place in the plastic bag provided with spill kit. 7.) Collect the dam and dispose of it in the plastic bag. 8.) Wash spill area with plenty of water. 9.) Dispose of pads, dam and plastic bag.

Transporting Chemicals
Job Hazard Analysis
Facility: Science Department Approved by: Science Dept. Date Revised: June 20, 2016 Step Description Hazard Controls 1 Determine the weight of the container from the label, if possible. Obtain a moving dolly or cart if necessary Accidental contact of incompatible materials. Carry only one chemical at a time, or if using a cart, do not transport incompatible chemicals in the same trip. 2 Prepare the desired destination for the container, keeping in mind possible need for isolation from other chemicals, ventilation, etc. 3 Lift any heavy containers carefully Possible back strain Lift carefully, or use a cart. 4 Glass bottles containing hazardous chemicals must be transported in an unbreakable container that is large enough to hold the contents of the bottle. Breakage or spillage of chemicals Use proper safety buckets and the like to hold the container. 5 Hold the container close to your body. Be certain others in the area are aware of your activity. An unexpected door opening could knock the container from your hands. Move slowly, pause at doorways, prepare the path you will take in advance, work at lower traffic times only.
