Inventory of toxic substances commonly used in chemical laboratories

The laboratory contains a variety of chemical substances and laboratory equipment supplies, a little inadvertent not only affects the results of the experiment, even heavy physical damage can occur. Below let us take a look at the toxic substances commonly used in chemical laboratories.

(1) Tris: Inhalation, ingestion, and skin absorption can cause injury. Wear gloves and goggles.

(2) Glycine: Inhalation, ingestion, skin absorption can cause injury. Wear gloves and goggles. Avoid inhaling dust.

(3) X-galactose (X-gal): It is toxic to eyes and skin. Follow the general precautions when using powder. It should be noted that the X-gal solution was prepared in an organic solvent (DMF).

(4) β-galactosidase: irritating, can produce allergic reactions. Inhalation, ingestion, and skin absorption can cause injury. Wear gloves and goggles.

(5) Phenylenediamine: Inhalation, ingestion, and skin absorption can cause injury. Wear gloves and goggles. Operate in a fume hood.

(6) Phenol: It is highly toxic and highly corrosive and can cause severe burns. Inhalation, ingestion, and skin absorption can cause injury. Wear suitable gloves and goggles, wear protective clothing, and operate in a fume hood. If you have skin contact medication, rinse with plenty of water and wash with soap and water. Do not wash with alcohol.

(7) Benzylsulfonyl fluoride (PMSF): a highly toxic cholinesterase inhibitor. Great damage to the mucous membranes, eyes and skin of the upper respiratory tract. Wear suitable gloves and goggles and operate in a fume hood. In case the eye or skin comes into contact with the drug, immediately flush it with plenty of water and discard the contaminated clothing.

(8) Benzoic acid: irritating. Inhalation, ingestion, and skin absorption can cause injury. Wear gloves and goggles and do not inhale.

(9) Benzyl benzoate: Irritating. Inhalation, ingestion, and skin absorption can cause injury. Avoid contact with your eyes. Wear suitable gloves and goggles.

(10) Phenylethyl alcohol: irritating. Inhalation, ingestion, and skin absorption can cause injury. Wear gloves and goggles away from fire, sparks and open flames.

(11) Acrylamide (unpolymerized): is a potential neurotoxin that is absorbed through the skin (with cumulative effects). Avoid inhaling dust. When weighing acrylamide and methylene bisamide powder, wear gloves and a mask and operate in a chemical fume hood. The polymerized acrylamide is non-toxic, but care should be taken when using it, as a small amount of unpolymerized acrylamide may be called up.

(12) Proteinase K: irritating. Inhalation, ingestion, and skin absorption can cause injury. Wear gloves and goggles.

(13) Propidium iodide: Inhalation, ingestion, skin absorption can cause injury. Irritating to eyes, skin, mucous membranes and upper respiratory tract. It can induce mutations and may cause cancer. Wear gloves and goggles, wear protective clothing, and handle carefully in a fume hood.

(14) Iodoacetamide: can base the amino group on the protein, thereby affecting the amino acid sequence analysis of the antigen. It is toxic. Inhalation, ingestion, and skin absorption can cause injury. Wear gloves and goggles. Operate in a fume hood, do not breathe dust.

(15) Sodium azide: It is highly toxic and blocks the cytochrome electron transport system. Solutions containing this drug should be clearly labeled. Inhalation, ingestion, and skin absorption can cause injury. Wear gloves and goggles and use with care. This medicine is an oxidizing agent, so keep it away from combustible materials.

(16) Paraformaldehyde: It is highly toxic. It is easily absorbed through the skin and is highly destructive to the skin, eyes, mucous membranes and upper respiratory tract. Avoid inhaling dust. Wear gloves and goggles and operate in a fume hood. Paraformaldehyde is an undissociated form of formaldehyde.

(17) 3,3'-Diaminobenzidine tetrahydrochloride: is a carcinogen and should be handled with great care. Avoid inhaling gases. Wear gloves and goggles. Operate in a fume hood.

(18) Xylene: flammable, high concentration of anesthesia. Inhalation, ingestion, and skin absorption can cause injury. Wear gloves and goggles. Operate in a fume hood. Always away from heat, sparks and open flames.

(19) Xylene blue: See xylene.

(20) Sodium methacrylate: may be a carcinogen and contains arsenic, which is highly toxic. Wear gloves and goggles and operate only in the fume hood.
