Тренировочный CES CBT тест онлайн по теме H2S Hydrogen Sulphide Awareness

Добро пожаловать на страницу, где вы можете пройти CBT тест (Computer Based Test), который еще называют CES (Crew Evaluation Test) онлайн по теме «H2S Hydrogen Sulphide Awareness» (влияние сероводорода на организм). Данная практика поможет вам, как морскому специалисту улучшить свои знания посредством электронного обучения и оценочной тренировки. Основанные на доказательных эмпирических данных и опыте морских специалистов, показательные и эффективные объединенные материалы CES/CBT тестов используются на практике в предметных областях.

Разработанные для оценки базовых знаний моряков CES & CBT тесты компании Seagull (после ребрендинга OTG) представляют собой онлайновый инструмент оценки, используемый для выявления потребностей в профессиональной подготовке, специфичных для областей знаний, определенных в ПДНВ.

В процессе отбора и набора персонала, а также для измерения уровня знаний существующих офицеров и экипажа, CES тест хорошо показал себя по всем параметрам. Ocean Technologies Group использовали для создания вопросов обширные темы, которые включают:

  • Управление кризисными ситуациями и скоплением людей;
  • Интегрированная навигационная система;
  • Управление балластными водами;
  • Обработка и укладка грузов;
  • Управление эксплуатацией судна и безопасностью;
  • Морская инженерия;
  • Техническое обслуживание и ремонт, и многие другие темы.

Данная страница содержит вопросы Seagull CES по теме «влияние сероводорода на организм», собранные из CBT тестового симулятора как для проверки компетентности команды судна, так и для личного тестирования знаний.

Тема «влияние сероводорода на организм» включает в себя теоретическую и практическую информацию, знание которой напрямую показывает профессиональность работника, занимающего соответствующую должность на борту судна. Знания, позволяющие иметь представление о физических и химических свойствах сероводорода, и симптомах его влияния на организм при контакте, использовать средства защиты, уметь обнаруживать и бороться с сероводородом на судне.

Crew Evaluation System Test на этой странице по теме «H2S Hydrogen Sulphide Awareness» содержит 35 вопросов, на которые надо дать ответ без возможности вернуться и изменить его, поэтому, советуем внимательно читать вопрос и не торопиться. В случае с затруднениями в любом вопросе есть возможность запросить подсказку правильного ответа.
