Embodiment 1

[0019] A risk decision-making method for semi-quantitative percutaneous exposure of chemical toxicants in petrochemical enterprises, such as figure 1 As shown, the chemical toxicant semi-quantitative transdermal exposure risk decision system of petrochemical enterprises is used to evaluate and determine the risk level of semi-quantitative transdermal exposure of chemical toxicants in petrochemical enterprises, and to provide different levels of skin exposure risk control management strategies. The system includes information collection modules, Skin hazard level assessment module, similar exposure group screening module, exposure factor data collection module, skin exposure level calculation module, skin risk level judgment module, skin risk control decision-making module; through information collection module and skin hazard level assessment module, petrochemical operation On-site information on chemical substances that may be exposed to the skin is available, and the skin haz...

Embodiment 2

[0028]A risk decision-making method for semi-quantitative percutaneous exposure of chemical toxicants in petrochemical enterprises, such as figure 1 As shown, a set of risk decision-making system for semi-quantitative transdermal exposure of chemical toxicants was established in order to systematically evaluate and control management of skin exposure.

[0029] (1) Information collection module: through standardized terminology questionnaires, the system collects information on chemical substances that may be exposed to the skin in petrochemical operation sites, including the amount of chemicals used, standardized operating procedures, material safety data sheets, toxicity data, occupational Chemical substances marked with "skin" in the exposure limit;

[0030] (2) Skin hazard level assessment module: link the chemical toxicity information obtained by the information collection module to assess the chemical skin hazard level according to the established skin hazard level assess...

Embodiment 3

[0058] Taking a refining and chemical enterprise as an example, common refining and chemical equipment includes atmospheric and vacuum units, catalytic cracking units, delayed coking units, hydrogenation combined units, etc. The chemical poisons that front-line operators may be exposed to through the skin mainly include alkanes, olefins, benzene and Its derivatives, petroleum, etc., this case takes the common n-hexane as an example. Protective measures include: the entire production process is pipelined, sealed, open-air framed, well ventilated, and automated control is implemented; outside operators operate in five shifts and three, working 8 hours a day, equipped with protective clothing, gas masks (worn when feeding), Masks, rubber and plastic-impregnated gloves.

[0059] Reasons for skin contact: accidental splashing of chemicals, exposure of skin in the air, and individual processes that make it inconvenient for workers to wear personal protective equipment.

Abstract

The invention relates to a petrochemical enterprise chemical poison semi-quantitative percutaneous exposure risk decision-making method, and mainly solves the problems of lack of chemical poison percutaneous exposure assessment methods and difficult management decision-making in the prior art. According to the petrochemical enterprise chemical poison semi-quantitative percutaneous exposure risk decision-making method, a petrochemical enterprise chemical poison semi-quantitative percutaneous exposure risk decision-making system is adopted to perform petrochemical enterprise chemical poison semi-quantitative percutaneous exposure risk grade evaluation and judgment and provide different grades of skin exposure risk control management strategies. The system comprises an information acquisitionmodule, a skin hazard level evaluation module, a similar exposure group screening module, an exposure factor data acquisition module, a skin exposure level calculation module, a skin risk level judgment module and a skin risk control decision module. The method can solve the problems well, and can be used in petrochemical enterprise chemical poison semi-quantitative percutaneous exposure risk decision.

Description

technical field [0001] The invention relates to a semi-quantitative transdermal exposure risk decision-making method of chemical poisons in petrochemical enterprises, which is used for risk level assessment and determination of chemical toxics percutaneous exposure and provides different levels of skin exposure risk control and management strategies. Background technique [0002] Most of the chemical poisons that workers in petrochemical enterprises come into contact with during operation are organic solvents (steam), mainly including benzene, toluene, xylene, ethylbenzene, gasoline, diesel, styrene, dimethylformamide, phenol, methanol, cyanide, etc. Dozens of hydrogen, acetonitrile, n-hexane, and inorganic acids and bases. Skin contact absorption is an important exposure route that causes systemic poisoning, which can lead to contact dermatitis, melanosis, occupational acne, occupational skin ulcers, and chemical dermatitis. Skin damage such as burns can also cause other sy...
