Face mask

Peel-off masks are applied in a uniform layer on the skin and upon drying and removal produce a sensation of skin tightness and cleansing action. Peel-off masks are marketed to consumers with normal, oily, combination, and acne-prone skin types. These masks are believed to perform the functions of skin exfoliation, hydration, and purification. They are based on plasticized polyvinyl alcohol. Hydrophilic emollients (e.g., ethoxylated fatty acid or alcohol derivatives, dimethicone copolyol) and humectants (e.g., glycerin, propylene glycol, sorbitol) are added to prevent moisture loss and cracking of polyvinyl alcohol film.

Acetic anhydride penetrates the skin quickly and painfully forming bums and bUsters that are slow to heal. Anhydride is especially dangerous to the deUcate tissues of the eyes, ears, nose, and mouth. The odor threshold is 0.49 mg/m, but the eyes are affected by as Httie as 0.36 mg/m and electroencephalogram patterns are altered by only 0.18 mg/m. When handling acetic anhydride, mbber gloves that are free of pinholes are recommended for the hands, as well as plastic goggles for the eyes, and face-masks to cover the face and ears. 

Laboratory work with hydrogen cyanide should be carried out only in a well-ventilated fume hood. Special safety equipment such as air masks, face masks, plastic aprons, and mbber gloves should be used. A chemical proof suit should be available for emergency. Where hydrogen cyanide is handled inside a building, suitable ventilation must be provided. The people involved should be thoroughly trained in first aid.

Cutaneous Cutaneous relates to or affects the skin. The term subcutaneous refers to being below the skin (as in a penetrating injury or injection). Use your MSDS to determine the required personal protective equipment (PPE) that you must use. Protecting the skin (with gloves, aprons, coveralls, face masks, etc.) is important. After all, the skin is the largest organ in the human body.

Respiratory protection The use of face masks, respirators, or separate air supply to reduce the intake of polhitants into the lungs. 

Heat exchanger surfaces need to he kept clean. Aqueous circuits (evaporator or condenser) can he cleaned with a chemical such as sulphamic acid, brushed or subjected to high-pressure water jets. In each case, all traces of dirt and chemical need to be removed from the circuit before it is put back to work. In cases of doubt, the manufacturer s advice should be sought. A layer of scale 2 mm thick on a condenser tube can cause a power increase of 16%, and the need to clean a condenser can usually be deduced from the condensing pressure. Persons using high-pressure water jets should wear face masks to avoid inhaling aerosol droplets. 

Because of the hazardous nature of anhydrous hydrogen fluoride, adequate precautions should he taken to protect the head, eyes, and skin. Rubber gloves, an apron, and a plastic face mask are strongly recommended. All operations should be carried out in a hood. If hydrogen fluoride comes in contact with the skin, the contacted area should be thoroughly washed with water and then immersed in ice water while the patient is taken to a physi-... 

Even the sampling of solids must not be casually undertaken, and the operator should always use a face mask as a protection until it is established that the powdered material is not hazardous. 

Endosulfan and metabolites were observed in the urine of workers who had prepared and applied endosulfan for 2-5 hours either 1 day or 1 week prior to sampling, without using protective clothing or face mask (thus, exposure was probably both dermal and inhalation) (Vidal et al. 1998). Unchanged a-and P-endosulfan and endosulfan ether were the predominant chemicals excreted 1 day following exposure. One week after exposure, a-endosulfan was detected in urine of four of five workers, but P-endosulfan was detected in only one of five samples and endosulfan ether was not detected at all. Endosulfan sulfate was detected in only one of five samples at 1 week after exposure and in none of the four samples at 1 day postexposure. Endosulfan lactone was detected in one of four and one of five samples at 1 day and 1 week after exposure, respectively. 

Epinephrine is widely used in clinical medicine for its multiple pharmacologic effects particularly for its potent vasoconstrictor effects. For example, in a dilute solution of 1 100,000, it provides a surgical tourniquet and facilitates a blood-free operating field. It is administered by nebulizer and face mask for post-intubation croup and for viral croup.

Less commonly, environmental monitoring can extend also to the operators in the manufacturing area whose clothing, e.g. gloves or face masks, may be sampled in order to estimate the levels and types of organisms which may arise as product contaminants fiom those sources.
