Storage & Handling

Recommended Storage
直射日光を避け、涼しく換気の良い場所に密閉して保管すること。内圧が上昇している可能性があるため、容器は静かに開けること。鋼またはポリエチレンを使用し、銅、黄銅、青銅、亜鉛、または亜鉛メッキの継手は絶対に使用しないこと。漂白剤、酸、およびハロゲンから遠ざけること。Adjudicated
Handling Precautions
Use in ventilation or with respiratory protection — vapour is the primary exposure. Chemical splash goggles and gloves. Open and transfer cool; pressure can build in warm sealed containers. Neutralization with acid is exothermic.Class-level guidance — not product-specific; the SDS controls.
Incompatibilities
漂白剤およびその他の次亜塩素酸塩、塩素、臭素およびヨウ素(有毒なクロラミンおよび爆発性化合物);水銀、銀および酸化銀、金(爆発性化合物);強酸(激しい反応、発熱);強酸化剤。銅、黄銅、青銅、亜鉛、亜鉛めっき表面およびアルミニウム合金を腐食する。Adjudicated
Shelf Life
Consult Technical Services for product-specific shelf life

For full hazard, PPE, and emergency response guidance, refer to the Safety Data Sheet (SDS) for this product. The SDS controls in all cases where guidance differs.
