You should be cautious while dealing with this chemical. This is a kind of oxidising chemical, and it could react exothermically with other chemicals. If contacting with combustible material may cause fire. Besides, it is irritant to eyes, respiratory system and skin, and it may cause inflammation to the skin or other mucous membranes. What's more, reacts violently with water, liberating extremely flammable gases. So you should take the following instructions to protect yourself. Wear suitable protective clothing, gloves and eye/face protection, and keep away from combustible material. If in case of contacting with eyes, rinse immediately with plenty of water and seek medical advice, and if in case of fire use ... (indicate in the space the precise type of fire-fighting equipment. If water increases the risk add - Never use water). Keep container tightly closed and dry. When store it, keep in a dry, cool and well-ventilated storeroom and then keep away from other organic matter, reducing agent and combustible things.
