Degreasing Powder AR-815 is a strongly alkaline industrial cleaning agent designed specifically for metal drill bits and precision components. Its hazard classifications include: Skin corrosion/irritation (Category 2), Serious eye damage/eye irritation (Category 1), and Respiratory irritation (Category 3). The hazard pictograms are GHS05 (Corrosive) and GHS07 (Exclamation mark), with the signal word "Danger". Major hazards are H315 (Causes skin irritation), H318 (Causes serious eye damage), and H335 (May cause respiratory irritation).
This product reacts violently with acids, generating significant heat, and is corrosive to amphoteric metals and light metals such as aluminum and zinc, potentially releasing hydrogen gas. It is prone to deliquescence and caking in humid air, and releases hydration heat when in contact with water. Therefore, strict risk control must be implemented in all aspects of operation, storage, and emergency response.
| Protective Area | Specific Requirements |
|---|---|
| Respiratory System | When dust or mist is generated, wear certified dust/particulate masks or half-face respirators; use only outdoors or in well-ventilated areas |
| Hands | Wear alkali-resistant protective gloves (e.g., nitrile rubber, neoprene) throughout, with a thickness of no less than 0.4 mm; pay attention to manufacturer's permeation data and replacement cycles |
| Eyes/Face | Must wear tight-fitting chemical splash goggles or full-face shields; do not substitute with ordinary frame glasses |
| Body | Wear chemical-resistant long-sleeved work suits, protective aprons, and slip-resistant alkali-safe safety shoes; contaminated clothing must be thoroughly cleaned before reuse |
Dilution sequence is critical: When preparing the solution, slowly add the powder to a pre-weighed quantity of cold water, never pour water directly into the dry powder to avoid localized overheating and splashing. Stir continuously to aid dissolution. Before operation, ensure emergency showers and eyewash stations are readily available. Avoid creating dust when handling; handle with care. Do not eat, drink, or smoke in the work area. After operation, thoroughly wash hands, forearms, and face with water and a mild cleanser; do not use organic solvents as substitutes.
Prohibited actions: Do not mix this product or its concentrated solutions with acidic substances; ensure tools and containers are free from residues of aluminum, zinc, and their alloys; check compatibility with drainage and public pipeline infrastructure.
| Accident Type | Response Measures |
|---|---|
| Inhalation | Move quickly to fresh air, keep respiratory tract clear, rest in a semi-sitting position; if breathing stops, immediately administer artificial respiration/oxygen and call for emergency medical assistance; even if symptoms subside, seek medical attention to rule out delayed pulmonary edema risk |
| Skin Contact | Immediately remove all contaminated clothing, rinse continuously with plenty of running water for at least 20 minutes (do not use hot water); if redness and burning pain persist, call a poison center or seek immediate medical attention |
| Eye Contact | Immediately open eyelids, rinse continuously with running water or saline for at least 15–20 minutes, frequently moving the eyeballs; if wearing contact lenses, carefully remove after 1–2 minutes of rinsing and continue rinsing; do not delay, call emergency services while rinsing, and immediately have an ophthalmologist treat |
| Ingestion | Do not induce vomiting; rinse mouth repeatedly with water; if conscious, give drinking water or milk; do not administer any liquid orally to an unconscious person; immediately call a poison center or arrange emergency medical treatment |
| Spillage | Non-emergency personnel should evacuate to a safe area; prevent powder from entering drains and natural water bodies; cover and absorb with dry sand, vermiculite, or other inert absorbent materials, mechanically sweep into designated alkali-resistant waste containers; do not flush spill site directly with water jets |
