The EMD Held a Quarterly Video Conference on Safety Management

The emergency management department held a quarterly Video Conference on centralized management of safety risks of hazardous chemicals

On July 29, the emergency management department held a quarterly video promotion meeting on the centralized management of safety risks of hazardous chemicals nationwide to report progress, analyze problems, exchange practices, strengthen measures, promote the implementation of key tasks, effectively prevent and control major safety risks, and create a stable safety environment for the success of the 20th CPC National Congress. Sunguangyu, member of the Party committee and vice minister of the emergency management department, attended the meeting and delivered a speech. Qichunxiao, the general manager of the group, and Qiao Huijie, the deputy general manager and director of safety and environmental protection, attended the video conference at the venue of the agricultural high-tech division in the Yellow River Delta.

However, from the mid-term evaluation results of centralized governance, there are still problems of uneven progress between regions, lagging progress of some special projects and low quality.

The meeting emphasized that we should have a clear understanding of the severe situation faced by the current safe production of hazardous chemicals and strengthen the sense of mission and urgency of doing a good job in centralized management. We should adhere to the problem orientation, anchor the goal of centralized governance, and make every effort to overcome difficulties. We should quickly wake up, be nervous, and take action. If there is a deviation in the direction of work, we should correct it in time. If the progress of work lags behind, we should pay close attention to make-up lessons, and accelerate the completion.

The meeting required that we should adhere to both the symptoms and root causes, accurately grasp the relationship between major risk prevention and control and centralized governance, promote major risk prevention and control and centralized governance as a whole, and prevent “two skins”. We should organically integrate centralized management and annual key work, integrate the requirements of centralized management tasks and measures into the major inspection of production safety and special safety actions, strengthen supervision and inspection and open and secret visits, do a good job in production safety in summer and flood seasons, strictly implement the main responsibility of enterprises, and resolutely prevent and contain major accidents and accidents with great impact.

At the meeting, Beijing, Liaoning, Zhejiang, Ningxia and other four provinces and CNPC made exchange speeches respectively, and the heads of relevant departments and bureaus, institutions and industry associations of the emergency management department and the main heads of relevant central enterprise safety management departments attended the meeting at the main venue; The heads of the emergency management departments at the provincial, municipal and county levels, as well as the relevant chemical parks and the main heads of enterprises attended the meeting at the branch venue.

Heptane Chemical Properties,Uses,Production

Chemical Properties

n-Heptane is a flammable liquid, present in crude oil and widely used in the auto- mobile industry. For example, as a solvent, as a gasoline knock testing standard, as automotive starter fl uid, and paraffi nic naphtha. n-Heptane causes adverse health effects in occupational workers, such as CNS depression, skin irritation, and pain. Other compounds such as n-octane (CH 3 (CH 2 ) 6 CH 3 ), n-nonane (CH 3 (CH 2 ) 7 CH 3 ), and n-decane (CH 3 (CH 2 ) 8 CH 3 ) have different industrial applications. Occupational workers exposed to these compounds also show adverse health effects. In principle, manage- ment of these aliphatic compounds requires proper handling and disposal to avoid health problems and to maintain chemical safety standards for safety to workers and the living environment.

Source

Schauer et al. (1999) reported heptane in a diesel-powered medium-duty truck exhaust at an emission rate of 470 g/km.
Identified as one of 140 volatile constituents in used soybean oils collected from a processing plant that fried various beef, chicken, and veal products (Takeoka et al., 1996).
Schauer et al. (2001) measured organic compound emission rates for volatile organic compounds, gas-phase semi-volatile organic compounds, and particle-phase organic compounds from the residential (fireplace) combustion of pine, oak, and eucalyptus. The gas-phase emission rate of heptane was 28.9 mg/kg of pine burned. Emission rates of heptane were not measured during the combustion of oak and eucalyptus.
California Phase II reformulated gasoline contained heptane at a concentration of 9,700 mg/kg.
Gas-phase tailpipe emission rates from gasoline-powered automobiles with and without catalytic converters were 1.82 and 268 mg/km, respectively (Schauer et al., 2002).

Environmental Fate

Biological. Heptane may biodegrade in two ways. The first is the formation of heptyl hydroperoxide, which decomposes to 1-heptanol followed by oxidation to heptanoic acid. The other pathway involves dehydrogenation to 1-heptene, which may react with water forming 1- heptanol (Dugan, 1972). Microorganisms can oxidize alkanes under aerobic conditions (Singer and Finnerty, 1984). The most common degradative pathway involves the oxidation of the terminal methyl group forming the corresponding alcohol (1-heptanol). The alcohol may undergo a series of dehydrogenation steps forming heptanal followed by oxidation forming heptanoic acid. The acid may then be metabolized by β-oxidation to form the mineralization products, carbon dioxide and water (Singer and Finnerty, 1984). Hou (1982) reported hexanoic acid as a degradation product by the microorganism Pseudomonas aeruginosa.
Photolytic. The following rate constants were reported for the reaction of hexane and OH radicals in the atmosphere: 7.15 x 10-12 cm3/molecule?sec (Atkinson, 1990). Photooxidation reaction rate constants of 7.19 x 10-12 and 1.36 x 10-16 cm3/molecule?sec were reported for the reaction of heptane with OH and NO3, respectively (Sablji? and Güsten, 1990). Based on a photooxidation rate constant 7.15 x 10-12 cm3/molecule?sec for heptane and OH radicals, the estimated atmospheric lifetime is 19 h in summer sunlight (Altshuller, 1991).
Chemical/Physical. Complete combustion in air yields carbon dioxide and water vapor. Heptane will not hydrolyze because it has no hydrolyzable functional group.

Shipping
