List of Hazardous chemicals

Acetic acid must be handled with great care. It may be harmful by inhalation, ingestion, or skin absorption. Wear appropriate gloves and goggles. Use in a chemical fume hood.

Bromophenol blue may be harmful by inhalation, ingestion, or skin absorption.

Wear appropriate gloves and goggles. Use in a chemical fume hood.

Chloroform, CHCl₃, is irritating to the skin, eyes, mucous membranes, and respiratory tract. It is a carcinogen and ,may damage the liver and kidneys. It is also volatile. Avoid breathing the vapours. Wear appropriate gloves, safety glasses. Always use in a chemical fume hood.

Copper sulfate, CUSO₄, may be harmful by inhalation, ingestion, or skin absorption. Wear appropriate gloves, safety glasses.

Ethanol(EtOH),CH₃CH₂OH, It may be harmful by inhalation, ingestion, or skin absorption.

Ethidium bromide is a powerful mutagen and is toxic. Consult the local institutional safety officer for specific handling and disposal procedures. Avoid breathing the dust. Wear appropriate gloves when working with solutions that contain this dye.

Formaldehyde, HCOH , is highly toxic and volatile. It is a carcinogen. It is readily absorbed by the skin and is irritating or destructive to the skin, eyes, mucous membranes, and upper respiratory tract. Avoid breathing vapours. Wear. appropriate gloves and safety glasses. Always use in a chemical fume hood. Keep away from heat, sparks, and open flame.

Giemsa may be fatal or cause blindness by ingestion and is toxic by inhalation and skin absorption. There is a possible risk of irreversible effects. Wear appropriate gloves and safety glasses. Always use in a chemical fume hood. Do not breathe the dust.

Hydrochloric acid, HCl , is volatile and may be fatal if inhaled, ingested, or absorbed through the skin. It is extremely destructive to mucous membranes, upper respiratory tract, eyes, and skin. Wear appropriate gloves and safety glasses. Use with great care in a chemical fume hood. Wear goggles when handling large quantities.

Isoamyl alcohol may be harmful by inhalation, ingestion, or skin absorption and presents a risk of serious damage to eyes. Wear appropriate gloves and safety glasses. Keep away from heat, sparks, and open flame.

Isopropanol is irritating and may be harmful by inhalation, ingestion, or skin absorption. Wear appropriate gloves and safety glasses. Do not breath the vapour. Keep away from heat, sparks, and open flame.

Liquid nitrogen can cause severe damage due to extreme temperature. Handle frozen samples with extreme caution. Do not breath the vapour. Wear a face mask.

Lysozyme is caustic to mucous membranes. Wear appropriate gloves and safety glasses.

Methylene blue is irritating to eyes and skin. It may be harmful by inhalation, ingestion, or skin absorption. Wear appropriate gloves and safety glasses.

Phenol is extremely toxic, highly corrosive, and can cause severe burns. It may be harmful by inhalation, ingestion, or skin absorption. Wear appropriate gloves, goggles and protective clothing. Always use in a chemical fume hood. Rinse any areas of skin that come in contact with phenol with a large volume of water and wash with soap and water; do not use ethanol.

Potassium chloride, KCl , may be harmful by inhalation, ingestion, or skin absorption. Wear appropriate gloves and safety glasses.

Proteinase K is an irritant and may be harmful by inhalation, ingestion, or skin absorption. Wear appropriate gloves and safety glasses.

Silver nitrate, AgNO₃ , is a strong oxidizing agent and should be handled with care. It may be harmful by inhalation, ingestion, or skin absorption. Avoid contact with skin. Wear appropriate gloves and safety glasses. It can cause explosions upon contact with other materials.

Sulfuric acid, H₂SO₄ , is highly toxic and extremely destructive to tissue of the mucous membranes and upper respiratory tract, eyes, and skin. It causes burns and contact with other materials (e.g., paper) may cause fire. Wear appropriate gloves , safety glasses and, lab coat. Use in a chemical hood.

Urea may be harmful by inhalation, ingestion, or skin absorption. Wear appropriate gloves and safety glasses.

UV light and/ or UV radiation is dangerous and can damage the retina of the eyes. Never look at an unshielded UV light source with naked eyes. Examples of UV light sources that are common in the laboratory include laminar air flow chambers and transilluminators. UV radiation is also mutagenic and carcinogenic. View only through a filter or safety glasses that absorb harmful wavelengths.

Xylene is flammable and may be narcotic at high concentrations. It may be harmful by inhalation, ingestion, or skin absorption. Wear appropriate gloves and safety glasses. Use in a chemical fume hood. Keep away from heat, sparks, and open flame.
