A. It complies with the test for viscosity (see Tests).
B. To 1 g in a test-tube add 0.5 ml of sulphuric acid, close the test-tube with a stopper fitted with a bent delivery tube and heat until white fumes are evolved. Collect the fumes via the delivery tube into 1 ml of mercuric chloride solution. An abundant white, crystalline precipitate is formed.
C. To 0.1 g add 0.1 g of potassium thiocyanate and 0.1 g of cobalt nitrate and mix thoroughly with a glass rod. Add 5 ml of methylene chloride R and shake. The liquid phase becomes blue.

Appearance of solution: The solution is clear and not more intensely coloured than reference solution.
Dissolve 12.5 g in water and dilute to 50 ml with the same solvent.
Acidity or alkalinity: Dissolve 5.0 g in 50 ml of carbon dioxide-free water and add 0.15 ml of bromothymol blue solution. The solution is yellow or green. Not more than 0.1 ml of 0.1 M sodium hydroxide is required to change the colour of the indicator to blue.
Viscosity: The viscosity is calculated using a density given in Table 1444.-1.
Macrogol BP2

For macrogols having a relative molecular mass greater than 400, determine the viscosity on a 50 per cent m/m solution of the substance to be examined.
Freezing point: See Table 1444.-2.
Macrogol BP3

Hydroxyl value: Introduce m g (see Table 1444.-3) into a dry conical flask fitted with a reflux condenser. Add 25.0 ml of phthalic anhydride solution, swirl to dissolve and boil under a reflux condenser on a hot plate for 60 min. Allow to cool. Rinse the condenser first with 25 ml of pyridine and then with 25 ml of water, add 1.5 ml of phenolphthalein solution and titrate with 1 M sodium hydroxide until a faint pink colour is obtained (n1 ml). Carry out a blank test (n2 ml).
Calculate the hydroxyl value using the expression: [56.1x(n2-n1)]m
Macrogol BP

For macrogols having a relative molecular mass greater than 1000, if the water content is more than 0.5 per cent, dry a sample of suitable mass at 100-105C for 2 h and carry out the determination of the hydroxyl value on the dried sample.
Reducing substances: Dissolve 1 g in 1 ml of a 10 g/l solution of resorcinol and warm gently if necessary. Add 2 ml of hydrochloric acid. After 5 min the solution is not more intensely coloured than reference solution.
Formaldehyde: Maximum 30 ppm.
competent authority may impose a limit of not more than 15 ppm.

Notes to Physician: Treat symptomatically and supportively.

Section 5 - Fire Fighting Measures

General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion.
Flammability: Combustible but not flammable.
Extinguishing Media: Use Water, dry chemical powder, alcohol foam, water spray or fog. Cool containing vessels with water jet to prevent pressure build-up, auto-ignition, or explosion.
Special Information: In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full face piece operated in the pressure demand or other positive pressure mode. At high temperatures under fire conditions, it may produce toxic or irritating fumes. Fire-extinguishing work is done from the windward and the suitable fire-extinguishing method according to the surrounding situation is used. Uninvolved persons should evacuate to a safe place.

Section 6 - Accidental Release Measures

Personal precautions, protective equipment, and emergency procedures: Avoid breathing dust/fumes/gas/mist/vapors/spray. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.). Restrict unprotected personnel from the area. Prevent any contact with hot surfaces. Do not approach facing the wind. Do not touch the spilled material.
Environmental precautions: Do not let the product enter drains, soil, or water sources.
Methods and materials used for containment Cleanup procedures and Storage: Use proper personal protective equipment. Restrict unprotected personnel from the area. Remove all ignition sources and ventilate area. Do not inhale dust, vapors, mist, or gas. Avoid dust formation. Contain spilled material. Cover with an inert, non-combustible absorbent material, (e.g. sand, earth, diatomaceous earth, vermiculite). Neutralize with sodium bicarbonate or calcium hydroxide, and deposit in a sealed bag or container. Use a shovel to put the material into a convenient waste disposal container. Use water spray to dilute spill to a non-flammable mixture. Finish cleaning by spreading water on the contaminated surface and allow to evacuate as per law.

Section 7 - Handling and Storage

Precautions for safe handling: Apply according to good manufacturing and industrial hygiene practices. Ensure proper ventilation. In case of insufficient ventilation, wear suitable respiratory equipment. Wash thoroughly after handling. Do not drink, eat, or smoke while handling. Avoid contact with skin, eyes, and clothing. Minimize dust generation. Avoid breathing dust/fumes/gas/mist/vapors/spray. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.). Prevent any contact with hot surfaces.
Conditions for safe storage, including any incompatibilities: Store in cool, dry, and ventilated area away from heat sources and protected from sunlight in tightly closed original container. Keep air contact to a minimum. Store protected from heat, sparks and ignition sources and incompatible materials. Avoid contact with skin and eyes. Avoid inhalation of dust/mist/vapor. Do not store with incompatible materials like strong oxidizing agents.

Section 8 - Exposure Controls, Personal Protection

Airborne Exposure Limits: Not available.
Ventilation System:
A system of local and/or general exhaust is recommended to keep employee exposures as low as possible. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area. Please refer to the ACGIH document, Industrial Ventilation, A Manual of Recommended Practices, most recent edition, for details.
Personal Respirators (NIOSH Approved): For conditions of use where exposure to dust or mist is apparent and engineering controls are not feasible, a particulate respirator (NIOSH type N95 or better filters) may be worn. If oil particles (e.g. lubricants, cutting fluids, glycerin, etc.) are present, use a NIOSH type R or P filter. For emergencies or instances where the exposure levels are not known, use a full-face positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do not protect workers in oxygen-deficient atmospheres.
Skin Protection: Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as appropriate, to prevent skin contact.
Eye Protection: Use chemical safety goggles and/or full face shield where dusting or splashing of solutions is possible. Maintain eye wash fountain and quick-drench facilities in work area.
Other Control Measures: Maintain good housekeeping in work area. Dust deposits on floors and other surfaces may pick up moisture and cause the surfaces to become slippery and present safety hazards. Handle in accordance with good industrial hygiene and safety practice. Wash hands after handling.
