Activities Involving Non-Laboratory Chemical Preparations：涉及非实验室化学制剂的活动

1、.Activities Involving Non-Laboratory Chemical PreparationsHazards:The non-laboratory use of chemical preparations (mixtures or solutions of two or more substances) is widespread throughout QMUL and includes use as adhesives, detergents, cleaning agents, dyes, inks, paints, pesticides, photographic d

2、evelopers and fixers and solvents. Such preparations are purchased and supplied for a specific purpose or use. Chemical preparations may possess the following hazards:· Toxic or harmful properties, including acute (immediate) or chronic (delayed) effects;· Corrosive or irritant effects;

3、83; Allergenic effects and respiratory or skin sensitisation;· Chemical and physical effects such as fire, explosion and dangerous reactive properties.Risk Factors:· Handling chemical preparations of unknown composition, those in unlabelled containers and those of unknown hazard;· Usi

4、ng any chemical preparation in a way which is contrary to the suppliers/manufacturers instructions;· Using any chemical preparation for a purpose other than that for which it is recommended or supplied;· Mixing together two or more chemical preparations unless this is specifically required

5、 by the suppliers/manufacturers instructions;· Storing chemical preparations in open, unstoppered, damaged or unlabelled vessels or containers;· Handling chemical preparations without appropriate personal protective clothing or equipment;· Storing, dispensing or using flammable chemic

6、al preparations near to ignition sources including flames, electrical equipment and hot surfaces;· Spraying chemical substances or applying them to any large surface in an unventilated area;· Handling large or heavy containers of chemical preparations including dispensing or transferring d

7、usty or liquid preparations from large to small containers without containment or control measures to prevent spills and splashes;· Handling or storing chemical preparations in areas where food and drink may be kept or consumed.Risk Control Measures:1. Use the least hazardous preparation consis

8、tent with the work to be done, use the least quantity and do not purchase or store more than is needed for the foreseeable future;2. Store chemical preparations in a safe and secure manner as recommended by the suppliers/manufacturers recommendation keeping incompatible preparations away from each o

9、ther and flammable preparations away from sources of ignition, after use return the preparation to its proper storage place;3. Use stock in chronological sequence of acquisition so that preparations do not deteriorate because of extended storage;4. Read the warning labels and/or safety data sheets a

10、nd learn about the hazards of the chemical preparation and the working practices for its safe use, if in doubt contact your manager or supervisor for further information or instruction;5. When handling dusty or volatile preparations, when applying them to large surfaces, when spraying or when using

11、open tanks or vessels containing chemical preparations whether they are health or fire hazards, it may be necessary to provide exhaust ventilation or personal respiratory protection;6. Do not siphon a chemical preparation by mouth however harmless it may appear;7. Gloves, eye protection and other pr

12、otective clothing may be necessary when handling any preparation which is toxic, harmful, corrosive, an irritant or cause allergy to prevent skin contact;8. Chemical preparations should be carried only in stoppered or sealed containers;9. Clean-up any spills or splashes especially on skin or clothin

13、g, wash the hands after handling chemical preparations and always before eating and leaving work;10. Dispose of residues and wastes according to the suppliers/manufacturers recommendations or through QMUL waste disposal procedures, label waste containers to describe the identity of the contents;11.

14、Cover cuts, grazes and other skin abrasions with a water proof dressing before handling any chemical preparation, wash cuts and wounds under running water and seek medical advice if they are likely to be contaminated.Persons at Special Risk:Those with a history of allergic or asthmatic symptoms who

15、routinely handle or work with respiratory or skin sensitizers (defined by risk phrase R42 “May cause sensitisation by inhalation” e.g. isocyanates, platinum salts, rosin core solder fumes and R43 “May cause sensitisation by skin contact” e.g. hydrazine and its salts, potassium dichromate, epoxy comp

16、ounds, formaldehyde and its aqueous solutions, acrylates).Health Surveillance:Those at special risk should report symptoms of respiratory sensitisation (periodic wheezing, chest tightness and breathlessness) or skin sensitisation (sore, red or itching skin) to their manager or supervisor who will ar
