• Intermitente – Defecţiunile intermitente reprezintă aproximativ 80% dintre defecţiunile legate de descărcările electrostatice. Procentul mare de defecţiuni intermitente se datorează faptului că momentul în care survine defecţiunea nu este observat imediat. Modulul DIMM primeşte un şoc electrostatic pe care îl absoarbe doar parţial ca o mică diferenţă de potenţial, fără să producă imediat simptome către exterior legate de defecţiune.
• Transportul componentelor sensibile – când transportaţi componente sensibile la ESD, precum piese de schimb sau piese care trebuie returnate la Dell, este esenţial ca aceste piese să fie introduse în recipiente antistatice pentru un transport în condiţii de siguranţă.
