Final answer:
To handle surfaces presumed contaminated, personal protective equipment and rigorous decontamination practices are essential, including the correct disposal of waste and aseptic techniques to prevent further contamination.
Step-by-step explanation:
When assuming all surfaces have been contaminated, it is crucial to follow strict decontamination protocols to ensure safety and prevent the spread of microbes. Personnel handling contaminated specimens or equipment, or those working with infected patients, should don personal protective equipment, including a protective coat, face protection, and cut-resistant gloves. After any skin contact, immediate washing with detergent and warm water is recommended, followed by cleansing with 1 N NaOH or a 1:10 dilution of bleach.
Contaminated waste must be safely disposed of through incineration or autoclaving in a strong basic solution, while all instruments require proper cleaning and soaking in this solution. Furthermore, aseptic techniques involving the disinfection of work areas and proper handling of bacterial culture spills are vital for maintaining a safe laboratory environment.
