Śrīmad Bhāgavatam 12.12.47

patitaḥ skhalitaś cārtaḥ
kṣuttvā vā vivaśo gṛṇan
haraye nama ity uccair
mucyate sarva-pātakāt

If when falling, slipping, feeling pain or sneezing one involuntarily cries out in a loud voice, “Obeisances to Lord Hari!” one will be automatically freed from all his sinful reactions.
