Identified Uses

Use of (di)antimony trioxide in PET (films/fibres, resin) production; Industrial use of (di)antimony trioxide in the plastics and rubber industry; Industrial use of (di)antimony trioxide in the manufacture of flame retarded textiles; Industrial use of (di)antimony trioxide in the production of glass, enamels, functional ceramics and semi-conductors; Industrial use of (di)antimony trioxide in the production of pigments, paints, coatings, ceramics, brake pads and production and formulation of fine chemicals; Industrial use of (di)antimony trioxide in wood adhesives; Professional uses of (di)antimony trioxide preparations; Professional uses of (di)antimony trioxide contained in articles. The major use of antimony trioxide is as a flame retardant. However, it does not itself have flame retarding properties; instead, it is a synergist for halogenated flame retardants in plastics, paints, adhesives, sealants, rubber, and textile back-coatings. Other uses of antimony trioxide include: polymerization catalyst in PET resin manufacture, clarifying aid in certain glasses, and pigments.

First Aid Measures

Emergency procedures for chemical exposure incidents

Inhalation

Move affected person to fresh air. Seek medical attention.

Skin contact

If normal occupational hygiene measures are maintained, there is no such foreseeable health hazard from antimony trioxide. Wash with water and remove clothes if necessary.

Eye contact

If normal occupational hygiene measures are maintained, there is no such foreseeable health hazard from antimony trioxide. Flush eyes thoroughly with water, also under eyelids.

Ingestion

If normal occupational hygiene measures are maintained, there is no such foreseeable health hazard from antimony trioxide. Rinse mouth with water.

Immediate Medical Attention

Not appropriate (see 4.2).

05

Firefighting Measures

Extinguishing media, specific hazards, and firefighter protection

Suitable media

Use fire fighting measures that suit the environment. The product is not combustible and does not support the combustion.

Unsuitable media

None.

Specific hazards

Antimony trioxide dust.

Firefighter Protection

Wear a self-contained breathing apparatus and a fully protective suit and gloves.

06

Accidental Release Measures

Spill cleanup procedures, containment, and environmental protection

Emergency procedures

Avoid formation of dust. Ensure adequate ventilation. Keep unprotected persons away. Avoid contact with skin, eyes, and clothing. Avoid inhalation of dust.

Environmental

prevented from reaching the sewage system or any water course and penetrating the ground/soil

Cleanup methods

Sweep all spilled material or use an appropriate industrial vacuum cleaner.

Materials: suitable containers or closed plastic bags

Handling and Storage

Safe handling precautions, storage conditions, and workplace requirements

Handling

Do not handle until all safety precautions have been read and understood. As a precautionary measure, the wearing of chemical resistant gloves, long sleeved overalls and closed footwear, designed to minimize skin contact is suggested for all antimony trioxide powder handling workplaces. Use personal protective equipment as required.

Storage

Store in well ventilated dry area. Do not store in open inadequate mislabeled packaging.

Hygiene

Avoid inhalation or ingestion. General occupational hygiene measures are required to ensure a safe handling of the substance. These measures involve good personal and housekeeping practices (i.e. regular cleaning with suitable cleaning devices), no eating, drinking and smoking at the workplace and wearing standard working clothes and shoes unless otherwise stated. Wash hands after use. Remove contaminated clothing and protective equipment before entering eating areas. Shower and change clothes at end of work shift. Do not wear contaminated clothing at home. Do not blow dust off with compressed air.

08

Exposure Controls / PPE

Occupational exposure limits, engineering controls, and protective equipment

Engineering

Prevent formation of dust where possible. Ensure appropriate ventilation/exhaustion at machinery and places where dust can be generated. Any deposit of dust which cannot be avoided must be regularly removed using preferably appropriate industrial vacuum cleaners or central vacuum systems. Waste air is to be released into the atmosphere only when it has passed through suitable dust separators.

Hands

Any dust-tight material (e.g. rubber-dipped cotton/rubber/nitrile/leather) suitable for the type of work (e.g. considering mechanical stress) could be used as material for gloves protecting against ATO exposure (non-corrosive inorganic substance). Breakthrough times are not relevant because corrosion and diffusion are excluded by the nature of the substance. Change gloves when damaged or according to manufacturer's instructions.

Eyes

Although the substance has no acute toxicity, it is advised to wear suitable safety glasses. NBN EN 166:2002 is recommended.

Respiratory

Use local ventilation to keep levels below established threshold values. A suitable particle filter mask is recommended.

Skin/Body

As a precautionary measure, the wearing of chemical resistant gloves, long sleeved overalls and closed footwear, designed to minimize skin contact is suggested for all antimony trioxide powder handling workplaces because of possible skin rashes when sweat ducts are blocked.

Environmental

Waste water generated during the production process or cleaning operations should be collected and should preferably be treated in an on-site waste water treatment plant which ensures efficient removal of antimony. Although the substance is not classified as dangerous to the environment, it is advised to avoid release to the environment.
