Spillage Procedures
/ First Aid Procedures:Personal Precautions: Use rubber, leather or fabric/composite gloves for hand protection. Wide vision full goggles to BS EN 166 grade 4B, with anit-mist for eye protection.. Long sleeved overalls, close fitting at openings. Boots that resist dust penetration.
Environmental Precautions: Avoid contamination of drains and watercourses. Spillage into watercourses must be alerted to the Environment Agency or other appropriate regulatory body.
Recover the spillage in a dry state if possible. Use vacuum suction unit, or shovel into bags. Cover or enclose area if possible to avoid unnecessary dust hazard. The material can be slurried by the addition of water but will subsequently set as a hard material. / Inhalation / Skin and eye contact / Swallowed / Injection
Irritating to the respiratory tract in high concentration. Remove from exposure and keep warm and at rest. Irrigate nose and throat with water for at least 20 minutes. / Skin – An irritant. May casue burns in presence of moisture. Remove contaminated clothing. Wash immediately with plenty of water.
Eye – Causes painful irritation and may casue serious damage to eyes unless immediate treatment is given. SPEED IS ESSENTIAL. Remove particles with cotton wool bud, irrigate with eyewash or clean water until medical help is obtained. Obtain medical attention as soon as possible. / Unlikely to cause any reactions. Larger doses may irritate gastrointestinal tract. Do not induce vomiting, wash out mouth with water and give copious amounts of water to drink / N/A
Guidance for the Completion of the COSHH Assessment Record Mentor
Most of the information to complete Tables A to D should be found in the Material Safety Data Sheet (MSDS) supplied with the product. If you do not have a material safety data sheet, you should contact your supplier and request one.
Table A
Assessor: Enter the name of the person carrying out the assessment.
Substance/Preparation name: The name of the substance/preparation should be entered here. This should be found on the product label or the MSDS.
Supplied by: Enter the name and address of the supplier/manufacturer of the substance/preparation.
Review Date: Enter the date that the assessment will be reviewed. This should be done on at least an annual basis or if there are any significant changes in the process, supplier etc.
Table B
Indication of Danger: This should be found on the product label and MSDS. There will also be an associated symbol on the label (e.g. a skull and cross bones on an orange background for a toxic product). Put a cross in the appropriate box under indication of danger. For Sensitiser, carcinogen, mutagenic and toxic for reproduction categories, you will have to refer to the MSDS and risk phrases on the label e.g. “may cause cancer” or “may cause birth defects”. Again put a cross in the appropriate box.
Route of Exposure: The route of entry or contact should be recorded here by putting a cross in the appropriate box. This information will be found in the risk phrases on the product label and in the MSDS, for example “irritating to eyes”, “may cause sensitisation by skin contact”, “may cause sensitisation by inhalation” etc..
Chemical State: A cross should be entered in the appropriate box.
Flammability: The appropriate information should be provided on the product label. The MSDS should provide information on the flash point (f.p.) of the substance/preparation.
Substances/preparations are classed as: Flammable if f.p. is < or equal to 210C; Highly Flammable if f.p. is < 210C; Extremely Flammable if f.p. is < 00C. Oxidising substances/preparations may cause fire or explosion in contact with combustible materials. Substances that are classified under these headings should be subject to separate detailed risk assessments with regard to their flammable properties, in addition to the health aspects considered in your COSHH assessment.
Volatility: This information should be provided in the MSDS. The relevant information is the boiling point (b.p.). Low volatility b.p. >1500C; Medium volatility b.p. between 500C and 1500C; High volatility b.p. below 500C. A cross should be placed in the appropriate box.
Dusty: This information should be provided for solids. A cross should be entered in the appropriate box. “Low” is applicable to pellet-like solids that do not break up and little dust is seen during use. “Medium” is applicable to crystalline, granular solids where dust is seen during use but this settles out quickly. “High” is applicable to fine light powders where dust clouds can be seen during use and these remain in the air for several minutes e.g. cement, chalk dust etc.
Table C
Hazardous substance/preparation composition (ingredients): The hazardous substance or constituents of the preparation should be listed in this section. These should be found in the MSDS.
Exposure Limits: The exposure limits for the hazardous substance/preparation should be outlined in the MSDS.
OES (Occupational Exposure Standard)
Exposure should be reduced at least to that level.
If the level is exceeded, suitable measures should be identified and implemented as soon as reasonably practicable to reduce exposure to the OES.
MEL (Maximum Exposure Limit)
Exposure should be reduced as far as reasonably practicable below the MEL and should not exceed the MEL.
Note that the absence of an OES or MEL does not indicate that it is safe.
Risk/safety phrases: The appropriate risk and safety phrases on the product label and the MSDS should be included in this section. Common Risk phrases include “Very toxic if swallowed”; “Causes burns”. Common safety phrases include “wear eye/face protection”; “Keep locked up and out of reach of children” etc.
Table D
Activity/Task: The activity or task where the substance/preparation is being used should be described in this section. This may include operations such as mixing, filling, spraying, cleaning, emptying, filling transportation storage etc.
Number of people affected and Occupation: The number of people that could be affected by the activity should be described in this section. People on each shift should be included. The occupation of the people should be included. People who are not directly involved in the process but could be affected by the activity should be described in this section, including risks to visitors or members of the public.
Quantities Used: The amount of the substance/preparation used in each operation should be estimated and a cross placed in the appropriate box. The larger option should be chosen if there is any doubt on the exact quantity used.
Duration of exposure: An estimate should be made of the time employees are exposed to the hazardous substance. The frequency of exposure should also be entered in this section e.g. three or four times a day, three or four times a shift etc.
Location and Conditions of Use: The location within the workplace should be described here and the conditions of use should be outlined, e.g. enclosed space, temperature.
Table E
Indication of Danger and route of exposure: List the Indications of Danger and routes of exposure identified in table B.
Existing Control Measures: Outline the existing measures that will reduce the risk of employee exposure to the substance/preparation. Check that they meet legal requirements, industry standards and represent good practice. Typical control measures include: engineering control measures e.g. general ventilation, local exhaust ventilation, (such as paint spray booths), total enclosure or containment of the process; personal protective equipment such as gloves, eye protection, overalls, respirators etc.
Risk: Assess the risks arising from the indications of danger and routes of exposure identified. When carrying this out consideration must be given to, what is reasonably foreseeable in relation to the identified hazards and recognition of the existing control measures that reduce the risk. Your assessment should be based on the information recorded in the previous tables. Enter the appropriate letter, L for low, M for medium or H for high. If the overall risk category is low, then the assessment is complete and the information contained within the assessment disseminated to those affected. However if the overall risk category is medium or high then additional control measures are required (see below).
Note: The definition of a RISK is:- the likelihood that harm from a particular hazard will be realized and consequences.
/LIKELIHOOD
SEVERITY / Certain or near certain to occur / Reasonably likely to occur / Very seldom or never occursFatality; major injury or illness causing long term disability
/HIGH

RISK
Additional Control Measures: Additional control measures that will reduce the risks further should be considered. . COSHH requires that exposure should be controlled by measures other than personal protective equipment so far as is reasonably practicable*. The following control measures should be considered to reduce the risk (A combination of control measures may be required).
1. Eliminate the need for the process or the use of the substance/preparation;
2. Substitute the substance/preparation with a less harmful alternative;
3. Total enclosure of the process;
4. Use plant, processes and systems of work, including training, that minimise the generation of, suppress or contain spills, leaks, dust, fumes and vapours;
5. Limit the quantities of the substance/preparation stored or used;
6. Local exhaust ventilation;
7. The reduction in the number of employees exposed;
8. Reduction in the period of exposure of employees;
9. Regular cleaning of contamination from walls, surfaces etc;
10. Provision of safe means of storage and disposal;
11. Provision of adequate facilities for washing, changing and storage of clothing, including arrangements for laundering contaminated clothing.
12. Personal protective equipment (Gloves, eyewear, shoes, overalls, respirators etc.).
completion date The date for the introduction of each control measure should be recorded.
Residual Risk: The assessment process must be repeated, taking into account, the existing and additional control measures. Enter the appropriate letter, L for low, M for medium or H for high. If the residual risk category is low, then the assessment is complete and the information should be disseminated to those affected. If the overall risk is medium then additional control measures should be introduced within the completion date period and the information contained within the assessment disseminated to those affected. If the Residual Risk remains high, work must not proceed and the risks arising out of the use of the substance/preparation reassessed to identify further risk reduction measures.
