Remove: Work clothing H2SO4 becomes wet or significantly contaminated should be removed and replaced. Change: No recommendation is made specifying the need for the worker to change clothing after the work shift. The actual determination of what constitutes an adequate quick drench facility depends on the specific circumstances, H2SO4.
In certain instances, a deluge shower should be readily available, whereas in others, the availability of water from a sink or hose could be considered adequate. Fabric legend and testing details. Normalized breakthrough times the time at which the permeation rate is equal to 0.
A different temperature may have significant influence on the breakthrough time; permeation rates typically increase with temperature. Unless otherwise stated, permeation was measured for single chemicals. The permeation characteristics of mixtures can deviate considerably from the permeation behavior of the individual chemicals. A blank cell indicates the fabric has not been tested.
The fabric may or may not offer barrier. More Info It is the user's responsibility to determine the level of toxicity and the proper personal protective equipment needed. The information set forth herein reflects laboratory performance of fabrics, not complete garments, under controlled conditions. It is intended for informational use by persons having technical skill for evaluation under their specific end-use conditions, at their own discretion and risk. Anyone intending to use this information should first verify that the garment selected is suitable for the intended use.
In many cases, seams and closures have shorter breakthrough times and higher permeation rates than the fabric. Please contact DuPont for specific data. If fabric becomes torn, abraded or punctured, or if seams or closures fail, or if attached gloves, visors, etc.

Caution: Sulfuric acid is extremely corrosive. Caution is advised. Signs and Symptoms of Acute Sulfuric Acid Exposure: Signs and symptoms of acute ingestion of sulfuric acid may be severe and include salivation, intense thirst, difficulty in swallowing, pain, and shock.
Oral, esophageal, and stomach burns are common. Vomitus generally has a coffee-ground appearance. The potential for circulatory collapse is high following ingestion of sulfuric acid. Acute inhalation exposure may result in sneezing, hoarseness, choking, laryngitis, dyspnea shortness of breathrespiratory tract irritation, and chest pain.
Bleeding of nose and gums, ulceration of the nasal and oral mucosa, pulmonary edema, chronic bronchitis, and pneumonia may also occur. If the eyes have come in contact with sulfuric acid, irritation, pain, swelling, corneal erosion, and blindness may result. Dermal H2SO4 may result in severe burns, pain, and dermatitis red, inflamed skin.
Emergency Life-Support Procedures: Acute exposure to sulfuric acid may require decontamination and life support for the victims. Emergency personnel should wear protective clothing appropriate to the type and degree of contamination. Air-purifying or supplied-air respiratory equipment should also be worn, as necessary. Rescue vehicles should carry supplies such as plastic sheeting and disposable plastic bags to assist in preventing spread of contamination.
Inhalation Exposure: 1. Move victims to fresh air. Emergency personnel should avoid self-exposure to sulfuric acid. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR.
If not breathing, provide artificial respiration. If breathing is labored, administer oxygen or other respiratory support. RUSH to a health care facility. Don't have a profile? H 2 SO 4 is formed naturally by oxidation of sulfide minerals in rocks.
Commercially, sulfuric acid is produced when sulfur trioxide is H2SO4 in water. A strong diprotic acid, sulfuric acid is colorless to slightly yellowish in appearance, sometimes cloudy. It is available in many grades or concentrations depending on the intended application. A common laboratory chemical, sulfuric acid is used as a reagent in many chemical reactions. Known historically as oil of vitriol and colloquially as battery acid, sulfuric acid sometimes spelled sulphuric has a variety of industrial uses, including:.
Sulfuric acid is an extremely dangerous chemical that must be handled with caution. Concentrated sulfuric acid should not be stored indoors in large quantities; it requires a cool, dry place away from direct sunlight, heating sources, and incompatible substances.
Exposure to sulfuric acid can occur via inhalation, ingestion, skin contact, and eye contact. Concentrated sulfuric acid has a severe effect on H2SO4 skin and eyes and can even cause permanent blindness. Ingestion of the acid can lead to death. Handlers are advised to follow safety precautions while working with sulfuric acid and to wear proper personal protective equipment PPE.
