Abstract. Employees are working on opencast coal mining from May to September
work in conditions of heating microclimate. A decrease in the influence of the high
temperature of air and solar radiation is reached by the uniform distribution of the hottest
time of day (from 12 to 16 o'clock) by drawing up the working schedule. The selection of
means of individual protection of hearing organs, their regular use, and efficiency assessment
performance will reduce the impact of noise on workers' bodies. Decrease of total working
time in conditions of exposure to industrial vibration not exceeding 5-6 hours will allow
reducing the class of working conditions on this factor. The effectiveness of individual
respiratory protection means the size of dust particles, the degree of insulation of the
underwear space in places where the mask is not tightly attached to the face. Considering dust
dispersion, working conditions classes of workers engaged in brown coal mining in
underground mine #9 "Angrenskaya" decreased by 1 stage, while in mine "Shargunkumir"
the working conditions classes on dust factor, on the contrary, increased by 1 stage.

FACE MASK HEALTHY OR UNHEALTHY- A REVIEW

The facemask is a personal protective equipment which is used to prevent the droplet or aerosol spread. Due to the pandemic spread like SARS, COVID-19 the mask is recommended to be worn by all the people to prevent the infection. It is one of the non-pharmaceutical ways of prevention, it helps in controlling the spread but not in complete eradication of the disease.This is a widely used way of prevention, which is cheap, non-invasive and has capacity to reduce the mortality rate due to respiratory infection. The major problem associated with these equipment are, they are commonly misused and they go out of stock even before the health care sector receives these equipment. So proper selection of masks is required to prevent the infection and also to reduce the demand of masks in the health sector. The aim of this review is to understand the importance of masks and needs of the personal protective equipment during the onset of any pandemic conditions. A systematic search strategy was done and the articles were found using keywords. Literature was taken from databases like PubMed and Google Scholar. The articles which discussed face masks were included and other articles which had the different types, advantages and disadvantages were also included. The review summarises the needs and the urge to use a face mask at the onset of pandemic condition. Selection of proper mask is emphasised to reduce the demand of masks.

COMPOSITION AND USES OF N95 MASKS -A REVIEW

The key aim of this article is to provide a description of the structure and uses of N95 mask that is necessary to advance Personal Protective Equipment ( PPE) during this COVID19 pandemic. Examples of personal safety gear designed to shield the user from infectious debris and from fluids contaminating the skin include the N95 respirators and medical masks (skin covers). A commercially available N95 respirator needs a suit factor of one hundred within the work-place to be deemed adequate. While we did not subjectively locate the respiration function needed with the prototype masks to vary from that necessary with a standard N95 filtering face device, this mask should not be used by people with respiratory risk of any sort. Although testers wear the masks easily for an hour, at any point in strenuous work or adverse environmental environments we can not think about their usefulness. This review offers detailed knowledge and appreciation of the structure, applications of N95 masks and, in turn, the advantages of N95 masks over other forms of surgical masks. Limitation and prospective range of the research were also addressed, as this subject is necessary to advance PPE in this COVID19 pandemic. This research contributes greatly to learning about the composition and uses of N 95 masks, and also helps to educate and make the general public informed of the critical role of N 95 masks during this pandemic assault.
