Well-designed engineering controls can be highly effective in protecting workers and will typically be independent of worker interactions to provide this high level of protection. The basic types of engineering controls are: ➢ Process controls which involve changing the way a job activity or process is done to reduce the risk. ➢ Enclosure and/or isolation of emission source which keeps a selected hazard “physically” away from the worker and ventilation that strategically “adds” and “removes” air in the work environment. Personal Protection: Eye and face protection: ➢ Safety glasses with side shields. ➢ Chemical goggles. ➢ Contact lenses may pose a special hazard; soft contact lenses may absorb and concentrate irritants. A written policy document, describing the wearing of lenses or restrictions on use, should be created for each workplace or task. This should include a review of lens absorption and adsorption for the class of chemicals in use and an account of injury experience. Skin Protection: ➢ See Hand protection Below Hand / Feet Protection: Personal Hygiene is a key element of effective hand care. Experience indicates that the following polymers are suitable as glove materials for protection against undissolved, dry solids, where abrasive particles are not present. ➢ Polychloroprene. ➢ Nitrile Rubber. ➢ Butyl Rubber.

These may be government mandated or vendor recommended. ➢ Certified respirators will be useful for protecting workers from inhalation of particulates when properly selected and fit as tested as part of a complete respiratory protection program. ➢ Use approved positive flow mask if significant quantities of dust becomes airborne. ➢ Try and avoid creating dust conditions.

Ingestion ➢ Although ingestion is not thought to produce harmful effects (as classified under EC directives), the material may still be damaging to health of the individual, following ingestion, especially where pre- existing organ (e.g. liver, kidney) damage is evident. ➢ Not normally a Hazard due to the physical form of product. The material is a physical irritant to the gastrointestinal tract. Skin Contact ➢ The material is not thought to produce adverse health effects or skin irritation following contact (as classified by EC directives using animal models). ➢ Nevertheless, good hygiene practice requires that exposure be kept to a minimum and that suitable gloves be used in an occupational setting. ➢ Open cuts, abraded or irritated skin should not be exposed to this material. Eye ➢ Although the material is not thought to be an irritant (as classified by EC Directives), direct contact with the eye may cause transient discomfort characterised by tearing or conjunctival redness (as with windburn) Slight abrasive damage may also result. Chronic ➢ Overexposure to the breathable dust may cause coughing, wheezing, difficulty in breathing and impaired lung function. Chronic symptoms may include decreased vital ling capacity and chest infections. Repeated exposures in the workplace to high levels of fine-divided dusts may produce a condition known as pneumoconiosis, which is the lodgement of any inhaled dusts in the lung, irrespective of the effect. This is particularly true when a significant number of particles less than 0.5 microns (1/50000 inch) are present. ➢ Amorphous silicas generally are less hazardous than crystalline silicas, but the former can be converted to the latter on heating and subsequent cooling. Inhalation of dusts containing crystalline Silicas may lead to silicosis, a disabling lung disease that may take years to develop. 8 Toxicity Irritation Dermal (rabbit) LD50: > 5000mg/kg [2] Not Available AEROSIL 200 Inhalation (Rat) LC50: 0.139 mg/L/4h[2] Oral (Rat) LD50: > 3300 mg/kg[2] Oral (Rat) LD50: > 5000 mg/kg[2] Toxicity Irritation Dermal (Rabbit) LD50: > 5000 mg/kg[2] Eye (Rabbit): Non-irritating * Silica Amorphous Inhalation (Rat) LC50: >0.139 mg/l/14h**[Grace] Skin (Rabbit): non-irritating * [2] Oral (Rat) LD50: 3160 mg/kg[2] Legend - Value obtained from Europe ECHA Registered Substances – Acute Toxicity 2. * Value obtained from manufacturers SDS.

Silica Amorphous ➢ The substance is classified by IARC as Group 3 ➢ NOT classifiable as to is carcinogenicity to humans ➢ Evidence of carcinogenicity may be inadequate or limited in animal testing. ➢ Reports indicate high/prolonged exposures to amorphous silicas induced lung fibrosis in experimental animals; in some experiments these effects were reversible. [PATTYS) Aerosil 200 & Silica Amorphous For Silica Amorphous: ➢ When experimental animals inhale synthetic amorphous silica (SAS) dust, it dissolves in the lung fluid and is rapidly eliminated. If swallowed, the vast majority of SAS is secreted in the faeces and there is little accumulation in the body. Following absorption across the gut, SAS is eliminated via urine without modification in animals and humans. SAS is not expected to be broken down (metabolised) in mammals.

Vendor Data ➢ For Amorphous Silica: Amorphous silica is chemically and biologically inert. It is not biodegradable. ➢ Aquatic Fate: Due to its insolubility in water there is a separation at every filtration and sedimentation process. On a global scale, the level of man-made synthetic amorphous silicas (SAS) represents up to 2.4% of the dissolved silica naturally present in the aquatic environment and untreated SAS have a relatively low water solubility and an extremely low vapour pressure. For Silica: ➢ Environmental Fate: Most documentation on the fate of silica in the environment concerns dissolved silica, in the aquatic environment, regardless of origin, (man-made or natural), or structure, (crystalline or amorphous). ➢ Terrestrial Fate: Silicon makes up 25.7% of the Earth’s crust, by weight, and is the second most abundant element, being exceeded only by oxygen. Silicon is not found free in nature, but occurs chiefly as the oxide and as silicates. Once released into the environment, no distinction can be made between the initial forms of silica. ➢ DO NOT discharge into sewer or waterways.

Each user must refer to laws operating in their area. In some areas, certain wastes must be tracked. A Hierarchy of Controls seems to be common - the user should investigate: ➢ Reduction ➢ Reuse ➢ Recycling ➢ Disposal (if all else fails) This material may be recycled if unused, or if it has not been contaminated so as to make it unsuitable for its intended use. ➢ DO NOT allow wash water from cleaning or process equipment to enter drains. ➢ It may be necessary to collect all wash water for treatment before disposal. ➢ In all cases disposal to sewer may be subject to local laws and regulations & these should be considered first. ➢ Where in doubt contact the responsible authority. ➢ Recycle wherever possible or consult manufacturer for recycling options. ➢ Consult State Land Waste Management Authority for disposal. ➢ Bury residue in an authorised landfill. ➢ Recycle containers if possible, or dispose of in an authorised landfill..
