Which of the following statements is correct regarding the safeguarding of machinery and users under safety regulations?

The question concerns requirements for safeguarding machinery and users under relevant safety regulations (e.g., Machinery Regulations in South Africa). Step 1: Analyze option a. The quality of material used and construction must suit the purpose, but this addresses design quality, not direct safeguarding during use. Step 2: Analyze option b. The transcription is unclear ("designed person must or she has premises"), but it appears to relate to design suitability for premises—not a core safeguarding measure. Step 3: Analyze option c. No person may be permitted to use or work on or near machinery unless competent or trained to the satisfaction of an inspector. This directly ensures user safeguarding through competency requirements. Step 4: Analyze option d. Precautions must be taken when machinery is in motion to protect people, and it cannot be set in motion unless made electrically live. This is likely incorrect or mistranscribed (safety typically requires electrical isolation, not energizing). The correct statement is option c. c
