Protection of Alcohols02:31

Protection of Alcohols

This lesson delves into the concept of protection and deprotection of a functional group fundamental to synthetic organic chemistry. These phenomena are explained in the context of aliphatic and aromatic alcohols.
Protection
It defines a protecting group as the masking agent to make the more reactive species inert to a given set of conditions. This concept is depicted via the illustration of liquid flow through different outlets in an assembly of pipes. The analogy helps to understand the role...
Hand hygiene01:23

Hand hygiene

Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Handwashing II: Pre-procedure and Initial Procedure Steps

The pre-procedure steps of handwashing include removing jewelry and rolling up sleeves. However, many organizations allow staff to wear wedding rings.
The hand washing procedure itself includes the following steps. First, cover cuts, if any, on hands with a waterproof dressing. Cuts and abrasions can become contaminated with bacteria hindering the ability to clean the area thoroughly. In addition, repeated hand washing can worsen an injury.  The nails must be short and clean, without nail paint...

Handwashing I: Introduction and Types of Equipment

Handwashing is hand hygiene with plain or antimicrobial soap and water to physically remove dirt, organic material, and microorganisms. However, it may not kill all microorganisms. The handwashing procedure requires a hand wash basin, liquid soap, paper towels, a domestic waste bin, and disposable nail cleaner as optional equipment.
Hand wash basins in clinical areas should have faucets that can be turned on and off without using the hands; that is, they should be non-touch or lever-operated.
Autoxidation of Ethers to Peroxides and Hydroperoxides02:23

Autoxidation of Ethers to Peroxides and Hydroperoxides

Ethers represent a class of chemical compounds that become more dangerous with prolonged storage because they tend to form explosive peroxides when standing in the air. Autoxidation is the spontaneous oxidation of a compound in air. In the presence of oxygen, ethers slowly oxidize to form hydroperoxides and dialkyl peroxides.
Physical Properties of Alcohols and Phenols02:32

Physical Properties of Alcohols and Phenols

Alcohols are organic compounds in which a hydroxy group is attached to a saturated carbon. Phenols are a class of alcohols containing a hydroxy group attached to an aromatic ring. The physical properties of the alcohols and phenols are influenced by hydrogen bonding due to the oxygen–hydrogen dipole in the hydroxy functional group and dispersion forces between alkyl or aryl regions of alcohol and phenol molecules.
Alcohols possess a higher boiling point than aliphatic hydrocarbons of similar...

Summary

Alcohol hand sanitizers pose an ignition risk, especially for smokers. Clearer warnings are needed due to widespread use in healthcare and public settings.

Area of Science:

  • Healthcare-associated infection control
  • Burn prevention
  • Public health safety

Background:

  • Alcohol-based hand sanitizers (ABHS) are widely used by healthcare professionals and the general public for hand disinfection.
  • ABHS are available in various forms, including gels, foams, and wipes, and are favored for their ease of use and rapid drying.
  • Strict protocols in healthcare settings mandate hand sanitization before and after patient contact.

Observation:

  • A case study involving a 40-year-old healthcare support worker who sustained flame burns after using alcohol-based hand gel.
  • The incident occurred in a clinical setting, highlighting a potential hazard associated with ABHS.
  • The patient was able to extinguish the flames, preventing severe thermal injury.

Findings:

  • Alcohol hand gels present a potential ignition hazard, particularly when used by individuals who smoke.
  • The flammability of alcohol-based hand sanitizers requires increased awareness among users.
  • This case underscores the need for enhanced safety information regarding ABHS.
  • Implications:

    • Clearer warnings regarding the flammability of alcohol-based hand sanitizers are necessary for both healthcare settings and the general public.
    • Public health campaigns should address the risks associated with ABHS use, especially concerning ignition.
    • Further research into safer alternatives or improved safety protocols for ABHS may be warranted.
