劳保用品不能“带而不用”

<正>前不久,笔者随同某企业工会、安监、劳动人事等部门组成的劳保用品佩戴使用情况专项检查组到生产一线检查职工劳保用品佩戴情况时发现,由于企业的强制性要求,职工上班基本上都带上了工作服、口罩、护目镜、手套、统靴、毛巾等劳保用品,但是劳保用品带到现场后却存在使用不规范,甚至带而不用的现象,令人堪忧。比如,有些职工干活时把本该戴上的口罩挂在胸前或者耳朵上,原因是嫌戴上口罩太热或呼吸不舒服;有些职工在进行电焊、切割作业时不戴护目镜,而是侧着身子迷着眼睛,这不仅存在安全

劳动防护用品与市场经济

劳动防护用品(简称劳防用品,亦称劳保用品)在计划经济时期,由若干专业生产企业生产,由国营专业商业垄断经营,由工矿企业使用单位的安技部门用公款购买,按照1963年劳动部公布的《国营企业职工个人防护用品发放标准》的规定,免费向劳动者提供,并要求劳动者在劳动生产期间使用。人们对它的认识比较浅薄,无论是生产厂家、经营企业、使用单位都没有倾注太多的关心,人们看重劳保用品的是社会效益,结果给劳保用品生产企业和经营企业带来了很大的经济效益,如北京市劳保商店当时一年的营业额相当于王府井百货大楼一年的营业额。从我国政府实行改革开放政策以后,随着市场经济机制的逐步建立,劳保用品被迅速推入市场经济的大潮中,发展迅猛,势不可挡。劳

Systematic patterns and random fluctuations in time series of coefficients of friction measured on floor surfaces

Coefficients of friction were measured periodically over a period of 30 months on the surfaces of five types of floor coverings in a new sport complex. The resulting time series were analysed with regard to both systematic and random short- and long-term effects of wear and maintenance. For detailed information about the involved wear mechanisms, two test sites characterized by different levels of pedestrian traffic were investigated for each floor covering. The systematic trends observed in time series of mean coefficients of friction were consistent with measured surface roughness parameters and could be divided into three categories, depending on the predominant wear mechanisms: smoothing of rough surfaces was accompanied by average monthly reductions of 0.007–0.014 in the coefficients of friction, measured under wet conditions, while mechanical polishing combined with coating by care products caused average changes between 0.002 and 0.006 per month. Progressive scratching and roughening of an initially smooth floor surface continuously increased the measured coefficients of friction by 0.003 per month. The cumulative long-term effects of surface wear exceeded the random variations in time series of mean coefficients of friction, characterized by a repeatability standard deviation of 0.006 and a reproducibility standard deviation of 0.020, respectively. For one specific floor covering, seasonal variations with an amplitude of 0.015 were observed in the time series of measured coefficients of friction.     

A review of the past,present and future of the European loss prevention and safety promotion in the process industries

In 2013, the European Federation of Chemical Engineering (EFCE) celebrates its 60th anniversary. EFCE has continually promoted scientific collaboration and supported the work of engineers and scientists in thirty European countries. As for its mission statement, EFCE helps European Society to meet its needs through highlighting the role of Chemical Engineering in delivering sustainable processes and products. Within this organizational framework the Loss Prevention Symposium series, organized throughout Europe on behalf of the Loss Prevention Working Party of the EFCE, represents a fruitful tradition covering a time span of forty years. The tri-annual symposium gathers experts and scientists to seek technical improvements and scientific support for a growingly safer industry and quality of life. Following the loss prevention history in this paper, a time perspective on loss prevention and its future is presented.

Numerical simulations on the attenuation effect of a barrier material on a blast wave

This paper numerically modeled previous experimental results and quantitatively revealed the attenuation effect of a barrier material on a blast wave. Four fluids were considered in the present study: the detonation products, water, foamed polystyrene, and air. These fluids were modeled by Jones-Wilkins-Lee (JWL), stiffened gas, and ideal gas equations of state. A mixture of water and foamed polystyrene was used as a barrier to encircle a 0.1 kg mass of spherical pentolite, and the interface problem between the barrier and the blast wave was investigated. The simulation parameters were the radius and the water volume fraction of the barrier. To elucidate the effect of the barrier, we conducted two series of numerical simulations; one without a barrier, and another with a barrier of 50 or 100 mm in outer radius and 0–1 in the water volume fraction. Peak overpressure, positive impulse, and pressure history all agreed well with the previous experimental results. We focused on the energy transfer from high-pressure detonation products to other fluids. The sum of the kinetic energies of the detonation products and the barrier induced by the blast wave could quantitatively estimate the attenuation effect of the blast wave and was minimized when the water volume fraction was 0.5, as was the case in the previous experiment.

Experimental study on thermal and toxic hazards connected to fire scenarios in road tunnels

The problem of toxic smoke in case of an accident with fire scenario is particularly severe in long tunnels and immediate effects from combustion product exposure often include fatalities. Notwithstanding extensive studies on fire simulation in tunnel, there is still a substantial lack of information on the different toxic products from combustion of light or heavy vehicles. In particular, there is a need for reliable test methods suitable to provide toxic products yields connected to defined accidental fire scenarios. In this paper, experimental runs in a laboratory scaled tunnel, simulating accidental fires of different heat release rates allowed firstly to characterize the thermal profiles in pool and car fires and to compare results by an analytical pool fire model. Results were compared as well with those obtained in a real scale tunnel, so as to quantitatively assess the scaling effect. A series of experiments was performed simulating an accidental scenario including pool fire from collision between a light vehicle and a HazMat heavy vehicle. An extensive set of experimental data allowed performing with good accuracy and reproducibility a complete characterization of toxic gases from car model fires, together with carbon monoxide and oxygen trends. The results obtained under different heat release rates allowed evidencing the dependence of the yields of toxic gases upon the considered scenario. Based on the intrinsic toxicity data of identified compounds, it is possible to draw practical conclusions, useful to assess the potential hazard associated to exposure to toxic smoke in road tunnel.     

Changes in the reaction regime during low-temperature oxidation of coal in confined spaces

A study of the initial stage of the low-temperature oxidation of coal is important, not only for the prevention for fires in coal industry, but also in reducing emissions of hazardous gases. A batch reactor was introduced and a series of simulated experiments of coal oxidation was carried out in this paper. The time-dependent rates of CO emission and oxygen consumption during oxidation experiments of coal samples with different particle size ranges were obtained simultaneously from the measurements of CO and O₂ concentration in the reactor. The experimental results show that the rate of CO emission presents three stages in the duration of coal oxidation. Based on the rates of oxygen consumption, the reaction order and reaction rate were obtained from the reaction rate equation. These results indicate that the reaction regime switches during coal oxidation in confined spaces. The initial decrease of reaction rate is due to the decrease of the active sites in coal. While the decrease of reaction rate in the following period of coal oxidation is attributed to the reaction-inhibition mechanism of oxidation products. And it is mainly represented by the chemisorption sequence of coal oxidation. The oxidative activity of coal can be restored when the oxidation products are evacuated. A mechanism of low-temperature oxidation of coal in confined spaces was also suggested.
