Covid-19 has brought about major changes for all people in various countries, for example creating vaccines, wearing masks and predicting the predictive state of death that will occur. In this paper, we will predict cases of covid-19 deaths using data taken from the worldometer website by taking data on daily covid-19 deaths worldwide in the period January 23rd- April 16th, 2020. Then the data is processed using the Poisson process that has been transformed using SPSS computer programming, namely the daily mortality rate in the period January 23rd - March 16th, 2020 using descriptive statistics, it was found that the death rate was 4 people in one day, then the Kolmogorov test followed the Poisson distribution, because it met the requirements for the P-value. value . Furthermore, it is calculated by using the death process, which is the chance of an event with the chance of death of all the corona suspects in the next 5 days, namely April 21 because the data has been transformed, so . the chance that no one will die within the next 45 days, namely April 30th, 2020 is close to. In the period of January  23rd  - April 16th, 2020 using descriptive statistics, it was found that the death rate was 6 people in one day, then the Kolmogorov test was carried out with the results following the Poisson distribution, because it fulfilled the requirements for a P-value . Furthermore, it is calculated using the death process, which is the chance of an event with the chance of death of all the corona suspects in the next 5 days, namely April 21st, 2020  because the data has been transformed, so . The chance that no one will die within the next 45 days, namely May 31, is close to .

<span lang="IN">Hydrogen sulphideor H2S is a naturally occurring gas found in a variety of geological formation. It is also formed by the natural decomposition of organic material in the absence of oxygen. It is encountered in a variety of industrial processes, including sewage and waste water treatment facilities and the production also refining of petroleum, pulp and paper, metals, acid gas, stink dump,vessels, etc.H2S gas is colorless, heavier than air and extremely toxic in small concentrations, it has a rotten egg smell, causes eye and throat irritation. H2S can deaden your sense of smell; at higher concentrations can causes death. For these reason training in how to protect you is crucial in any industry and places where H2S might be encountered. You will know more about the toxic effect and dangers of H2S, but first take a look at the following fatality incidents, which occurred in the petroleum industry. All of this incident could have been prevented.The data were collected by using study of literature and observation.the suggestionto overcome the problem are cautions when dealing with any confined space and if near oil and gas facilities check wind direction.</span>

<p>A job has the potential of causing serious injuries or death. It is necessary to formalize agreed upon work procedures. This prevents the instructions from being missed, forgotten or misinterpreted. It also works as a checklist to ensure that all the hazards, protective measures, work procedures and the general requirements are reviewed with and understood by the assigned worker(s). A work permit serves as a record of the authorization and the completion of the specific work. The authorization must be provided by the competent person after all the necessary conditions have been met. The purpose of this study is to familiarize permit to work system on board of a ship for a safe working environment. The data collecting method use is library research. All parties, the company, the officers and the assigned worker(s) have to commit and comply to all procedures and the requirements of the permit to work system. It has been provided by the regulator. It should be used as needed and required. K</p><p><em><strong>Keywords :System, Work permit, Safe working, Board, Ship</strong></em></p>
