Step-by-step explanation:
For maximum safety, an electrician should learn all OSHA standards and requirements by heart. These standards are designed to protect workers from serious hazards in various industries, including the construction and electrical fields. Additionally, an electrician should be familiar with and adhere to every NEC code. The National Electrical Code (NEC) provides guidelines for safe electrical installations and is regularly updated to reflect new technologies and safety practices.
While the other options mentioned in the question, such as performing tasks with one hand or in low light situations, may have some relevance to electrical safety, they are not as critical as knowing the OSHA standards and NEC codes. These resources provide comprehensive guidelines and regulations to ensure maximum safety.
